Question
A square coil of side 25 cm having 1000 turns is rotated with a uniform speed in a magnetic field about an axis perpendicular to the direction of the field. At an instant t, the emf induced in the coil is e =200sin 100
. The magnetic induction is
- 0.50 T
- 0.02 T
- 0.01 T
The correct answer is: 0.01 T
