do we have any prof of such planets existing?
They have been verified through telescopes, and probes have been sent to them. One such planet with no magnetic field is Mars. The following website summarizes many of the probes that have visited Mars. http://www-ssc.igpp.ucla.edu/personnel/russell/papers/mars_mag/

Well maybe, Like Edward says in his book that voltmeters are only one sided.. So what is being understood is not the full scope of the EM spectrum. In a Toroidal body of a planet the horizontal equator line which is noted as a slight bulge is the indication of a Double Torus, the gif animation shows the cause of this. This means the equator is a 3rd polarity or neutral pole. The EMF is a part of gravity.
Think of it like this all matter and energy is existing on various octaves, wavelengths or channels of the same space and each form of matter/energy has a different threshold of infinite depth that is accessed by its quality centred on a different octave/channel to every other form of matter/energy of the same quantified space. However it isn't a linear depth as in down but a within inward centralised depth so Gravity being the most expansive phenomena encompasses all other frequencies of depth, thus like Russian dolls next comes epsilon waves, gamma, ultraviolet, infra-red/heat/light, sound, electromagnetism and then atomic. they all exist with same volume of space but at various wavelengths of depth which are shorter than gravity...hence gravity encompasses them, because it is expansive it cycles slower and has a more permeable quality about it.
The essence of Gravity can be understood to be similar to how a quantified bracket of measurement on ruler when placed over an elastic band will show that the amount of existing mass from within the range of bracket of measurement is decreased as the elastic is stretched. Hence gravity is a wide thin waveform but there is a hidden factor which gives its thinness a mighty quality. Effectively gravity is a carrier wave by which all other phenomena manifest through, But the aspect of which mainstream science has not understood yet is that all waveforms have 2fold manifest qualities (i.e. macro and micro cosmic)
First is the wavelength by which their effect occurs phenomenally speaking:
e.g. gravity is an agglutinising phenomena that grounds things; so it has a slow active waveform in the macro level of the cosm. As analogy think of sound and how fast high treble frequencies cannot penetrate the walls of a room as easily as slow sub bass frequencies. This is because they are shorter wavelengths and so more cycles occur in which the peak of their cycle creates friction against the matter particles in the wall, thereby absorbing energy and slowing the speed at which they move through i.e. the damping out effect where high frequencies become lower as they are absorbed by mass and thus get quieter at the same time. On the other hand bass that is pumping out at the same relative threshold of amplitude as the treble is already slower in frequency, so the number of cycles that can create friction with the wall is less, thus it slips though much easier with more yield of volume on the other side. So the phenomenally active quality of gravity is like sub bass.

The second quality is the quantum/microcosmic function of a waveform:
i.e. the undetectable aspect of the waveform which augments its phenomenal frequency; the quantum components/quantum foam arrange and trigger clusters patterns that produce the waveform:The quantum foam is akin to a colloidal silver solution; positive electromagnetically charged monatomic silver particles repulsed by each other and thus suspended in a liquid medium as equidistant points. In the imploverse this is the equivalent of quantum-components imploding with infinite depth - inward implosion, whilst repulsed equally by one another by the equal charge of their outer envelope.
The smallest quantum components are
micro Tori (mT) which have an Implosive charge of depth
(Dch). The neutral charge of space is actually mT collectively expressing this exponential frequency of implosive Dch which exceeds the Dch of all manifest phenomena i.e. an
infinitive-waveform (Iw). The mT of the quantum foam thus exhibit this exponential Iw Dch in unison when matter or energy is absent , and this produces the appearance of seemingly empty space. The
Master-Macrocosmic Torus (MMT) of an Imploversial cosmos encapsulates all mT of its cosm and the Dch of its fundamental waveform encompasses them all. So, the MMT supports the seemingly empty space Iw Dch of mT with the fundamental carrier wave of it's implosive scope. Thus the Dch of MMT causes the mT of its quantum foam to all shrink by equal measure into the infinite depth of the Cosm's Imploversial scope.
When matter or energy is present the Dch of mT still implode infinitesimally but the rate is a slower speed, so a ratio of Dch contrast is produced between mT that express empty space and those that express manifest phenomena. The phenomenal waveforms have at least two slower speed Dch rates than the exponential Iw of empty space, this enables them to express cyclic frequency as opposed to exponential uniform Iw's. The multiple alternating speeds of Dch of cyclic phenomena create ripples of illusory movement i.e. like LED lights on a grid turning on and off in succession producing the illusion of a single light moving across space; this is called scalar movement. These ripples of cyclic phenomena mimic the Torus shape of the cosm. So that from the defined scope of a given cyclic phenomenon's presence the scalar ripples move inward along the vertical Axis from both poles of the Torus shape that they mimic, whist also moving outward from the centre/equatorial disk. In the case of a material particle such as an atom there are multiple scalarly mimicked Tori that move as clusters of scalar movement, which in turn create cluster based scalar-ripples of which form the atomic Torus by which in comparison is a standing wave cluster, which moves only when another atomic Torus cluster in motion comes into contact with it whereby the collective Dch frequency signature of the moving atom has a repulsive effect on the standing wave atom.
__________________________________________________________________
waveforms of energetic phenomena occur in scalar wave/particle patterns that are ripples being either repulsed out of, or attracted into the vortation of a core frequency of an atomic Torus cluster, whereby the matrix of harmonic Dch arrangements creating the atom/particle-Torus, manifest repulsive or attractive EM fields due to all mT's being innately magnetic themselves. As this happens the smaller tori cluster patterns of the energetic phenomena scalarly travel into the donut of the atomic (or whichever particle in question) Torus, thus adding more energy to its core harmonic Dch frequency than it naturally accommodates. Thus the excess energy is scalarly pulsed out from the equatorial disc in a radial manner or as discharge out of either or both ends of the north and south axis like the beam of discharge that is seen emanating from the centre of galaxies. The variable harmonic matrices of any given Torus/element as well as the kinds of particles absorbed by them determine a wide variety of discharge patterns. i.e. straight beams, splayed funnel beams both single or double ended, and then different velocity and amplitude equatorial ripples. When all of them occur at once in more or less equal measure omni directional phenomena such as sound and light/radiation result, this is the general default in nature but in electronic devices arrangements of uncommonly met clusters produce accentuated pulses of radiation such as a laser beams etc.
All cyclic frequencies are embedded in the spectrum of Dch which is occupied by Gravity, which itself is a Torus shape but on a higher frequency band of mT cyclic Dch and wider macrocosmic expanse than anything else, meaning its ratio of lesser Dch acceleration in contrast with the Iw acceleration of empty space, is the fastest rate than any other cyclic phenomena and thus the shallowest in contrast with empty space. The wider the expanse of a Gravitational field the more ripples of its scalar cycles there are flowing inward, creating a cumulation of stronger/more frequent Gravitational pressure as it approaches the core of it's toroidal vortex. This would be synonymous with the expanse of the sun's
__________________________________________________________________
So, this explains how gravity is the slowest cycling macrocosmic phenomenon produced by the scalar ripples of the fastest accelerating Dch frequencies in the mT of the quantum/microcosmic foam, akin to how the elastic band becomes very fine in mass over its length when stretched; The fineness is akin to the thinness of the ratio of gravity's mT in contrast with the uniform mT Iw's of empty space, and the stretched length is akin to the greater quantity of time it takes for a single cycle to complete (being the slowest phenomena) this explains why the phenomenal effect of Gravity is so little in the quantum world. All other cyclic phenomena access greater contrast of dch with the Iw's of space and exist embedded within the Dch scope of Gravity as was described earlier with the Russian dolls analogy.
In other words all phenomenal frequencies have faster cyclic speeds in their macrocosmic expressions as they proceed up the spectrum from Gravity to atomic/quantum particles, sound/electromagnetism, light/ heat/infra-red, ultraviolet, gamma and epsilon. As they become quicker cycles in the macrocosmic level, the Dch acceleration on the quantum level becomes slower and slower in contrast with the exponential Iw's of empty space. So, the elastic band analogy is useful here too, i.e. all phenomenal energy and matter utilise the same fundamental volume of mT Iw Dch which is depleted/become shallower in acceleration as they become higher finite frequencies in the macro-cosmos. A shallower volume/ slower acceleration of mT Dch means faster finite frequencies (energy), and a greater volume/faster acceleration of mT Dch means slower finite frequencies (matter mass) gravity fits into the matter mass spectrum, as a very slow frequency that cannot produce a tangible quality.
This is why all though gravity is called the weakest charge/slowest force, this is only in the experiential macrocosm, thus it is simultaneously the strongest charge/fastest force of quantum mT Dch having the greatest wavelength of Dch, hence it is the carrier wave which holds in ite own Dch the potential for all other forms of phenomena to manifest through. As such gravity holds hidden qualities (psuedo-forms) of all other types of energy except there is no definition of finite length to the qualities it contains, they rather exist as a collapsed unified ultimate force which has influence over all possible defined lengths of phenomena that it's spectrum encompasses.
Hence gravity has an EM effect in its own domain i.e. binding all other things to its common core of influence

Conclusion:
Perhaps the EM particles that stream out from the sun thereby causing a planet to spin as Ed describes, continue to make it spin when a planet's mean EM spectrum has gone dormant due to bio-spheric degradation, such as the case of Mars it is known that Mars still has gravity which by what I have extrapolated about mT Iw's implies it has an EM quality in its Gravitational fields own mean band of it's total spectrum. We know that the Earth's EMF is partially caused by piezoelectric effect of quartz under pressure within the crust. Ed mentioned Voltmeters and such only measure positive electricity, so the known EM spectrum is only partial...thus if a planets bio-spheric EMF that can be measured is not measurable this does not necessarily mean the total EM spectrum responsible for Gravity is missing, no doubt Mars may still have some sort of piezoelectric effect emanating from in the crust.
