Question

Find out charge flow when coil rotates by an angle 180°​

Answer 1

Answer:

here u r answer

Explanation:

The induced emf in coil due to changing flux through it due to rotation of it is given by

EMF=−N

dt

dϕ

When the rotation direction of the coil is changed,

dt

dϕ

reverses its sign, and so does the emf.

Hence due to reverses potential difference in the attached circuit, the current also reverses its direction.
