electromagnetism

I''m wondering, does a magnetic field change the number of electrons, placed and displaced on the two plates of a capacitor. To prove or disprove this, I think the capacitor could be connected to an other capacitor outside the magnetic field and it has to be measured the current flowing between the capacitors during the increase and …

Revisiting the Charging–Capacitor Problem: Maxwell''s …

But, if the current responsible for charging the capacitor is time-dependent, this will also be the case with the magnetic field outside the capacitor. This, in turn, implies the existence of an "induced" electric fiel d in that region, contrary to the usual assertion that the electric field outside the capacitor is zero.

The cathode is built into the center of an evacuated, lobed, circular chamber. A magnetic field parallel to the filament is imposed by a permanent magnet. The magnetic field causes the electrons, attracted to the (relatively) positive outer part of the chamber, to spiral outward in a circular path, a consequence of the Lorentz force.
