A WIRE MOVES ...

Question

A WIRE MOVES WITH SOME SPEED PERPENDICULAR TO MAGNETIC FIELD. WHY IS EMF INDUCED ACROSS THE ROD?

Open in App

Solution

The e.m.f is induced in the wire due to its motion perpendicular to the magnetic field. The magnetic flux linked with the wire changes with time and thus, the e.m.f is induced across its ends.
