When a conducting rod is moving in a uniform magnetic field (rod, magnetic
field, velocity mutually perpendicular) charge accumulation establish at the
ends of the rod. If the rod slides along a stationary U-shaped conductor, an
induced current is established around the circuit.
My question is about the motion of the electrons of the U-shaped conductor
when these electrons reach the moving rod: Do the electrons from the U-shaped
conductor go inside the rod?
An excellent analysis about the motion of electrons has been made bybrian whatcott <inet@intellisys.net>
Young-Freedman (University Physics- ninth edition pg. 953) But they don' t
mention what happens if the electrons of U-shaped conductor reach the moving
rod.
I have another question about the electrons' motion in the U-shaped
conductor and rod. Suppose that the rod has big length, bigger than the
opening of the U-shaped conductor so its ends exceed the U-shaped
conductor. What happens with the electrons? Do they accumulate at the point
of the rod, where the rod meets tha U-shaped conductor? If so, why does this
happen? Don't forget that the whole rod is inside a uniform magnetic
field....
Thank you
