Why doesn't Venus have a magnetic field ? In part because of its slow rotation (243 days) and its predicted lack of internal thermal convection, any liquid metallic portion of its core could not be rotating fast enough to generate a measurable global magnetic field.

Saturn - Saturn - The magnetic field and magnetosphere: Saturn's magnetic field resembles that of a simple dipole, or bar magnet, its north-south axis aligned to within 1° of Saturn's rotation axis with the centre of the magnetic dipole at the centre of the planet. The polarity of the field, like Jupiter's, is opposite that of Earth's present field—i.e., the field lines emerge in ...

Jan 12, 2015· This is a great question. Any time a magnet is pointing against an applied magnetic field (as happens when you push two north poles or two south poles together) there is indeed a "pressure" associated with their repulsion. If the applied magnetic field is strong enough, then it can make the permanent magnet "pop", just like you suspected.

Aug 21, 2014· When a magnetic field gets stronger than about 500,000 Gauss, objects get ripped to pieces by the intense forces. For this reason, scientists cannot build a machine that creates a magnetic field stronger than 500,000 Gauss and survives longer than a fraction of a second. Strong enough magnetic fields therefore destroy objects as we know them.

The advantage is that intensity of electric field will not reduce even at large distance from the sheet. I don't know how you would manage to have such sheet, but little approximated one would help. For magnetic field, you can't have a plane sheet as you had for the purpose of electric field, the reason is magnetic monopole don't exist.

The existence of Jupiter's magnetic field was first inferred from observations of radio emissions at the end of the 1950s and was directly observed by the Pioneer 10 spacecraft in 1973. Jupiter's internal magnetic field is generated by electrical currents in the planet's outer core, which is composed of liquid metallic hydrogen.
