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 time
e.M.F induced in the coil is e = 200 sin 100 t. The magnetic induction is:

Answer:
B=0.01t
Explanation:
An emf is prompted withinside the coil whilst a bar magnet is driven inside and out of it. Emfs of contrary symptoms and symptoms are produced through movement in contrary directions, and the emfs also are reversed through reversing poles. The equal effects are produced if the coil is moved instead of the magnet—it's far the relative movement this is important.
E=200sin100πt
Eo=200 .
w=100π
we recognise that
wxBAN=Eo
B=Eo/ANW
B=200/(0.25²)x1000x100π
B=0.01t
