Question

A circular loop is initially placed in a uniform magnetic field perpendicular to the field lines and then removed quickly from the field. The induced emf causes the electric charge flow in the loop . Explain the force on the induced current due to the original field

Answer 1

The induced emf is found as -0.0531 V. When the flux coupling with a conductor or coil changes, electromotive Force, or EMF, is said to be induced.

What is induced emf?

Emf is the production of a potential difference in a coil as a result of changes in the magnetic flux passing through it.

From Lenz law,the the induced EMF is found as;

$\rm e=- \frac{\triangle \phi _B}{\triangle t } \\\\\rm e=- \frac{A\triangle B}{\triangle t } \\\\ e= -\frac{\pi r^2(0-1.10)}{0.15} \\\\ e=-0.0531 \ V$

Hence,the induced emf is found as -0.0531 V.
