a current can be induced to flow in a coil in which of the following situation?
a current can be induced to flow in a coil in which of the following situation?
Homework Answers
when the flux through coil is changed .it can be due to changing
the area or changing the magnetic field or by rotating the coil emf
= -d/dt where
=B .A B
is magnetic field and A is area vector as there is change in flux
current flows
