A small piece of metal wire is dragged across the gap between the pole pieces of a magnet in 0.5 s. The amgnetic flux between the pole pieces is known to be 8 xx 10^-4 Wb . Estimate the e.m.f. induced in the wire.

Between dissimilar poles of the magnet there is-

A small retangular coil ABCD contains 140 turns of wire. The sides AB and BC of the coil are of length 4.5 and 2.8 cm respectively, as shown in the figure The coil is held between the poles of a large magnet so that the coil can rotate about an axis thorugh its centre. The magnet produces a uniform magnetic field of flux density B between its poles. When the current in the coil is 170 mA, the maximum torque produced in the coil is 2.1 xx 10^-3 N m . Use your answer to show that the magnetic flux density B between the poles of the magnet is 70 mT.

A satellite with a 40 cm long copper wire on its bottom is revolving around the earth at 7.8 km per second, such that the wire is perpendicular to the vertical component of earths' magnetic field. Determine the e.m.f. induced across this wire, if the magnitude of the vertical component of magnetic field is 0.2 gauss.

What is the relationship between e.m.f. and magnetic flux?

How does induced e.m.f. depend upon the change in magnetic flux?

Two identical magnetic with a length 10 cm and weight 50 g of each are arranged freely with their like poles facing in a inverted vertical glass tube. The upper magnet hangs in the air above the lower one so that the distance between the nearest pole of the magnet is 3mm. Pole strength of the poles of each magnet will be
