A coil of `40 Omega` resistance has `100` turns and radius `6 mm` us connected to ammeter of resistance of `160 ohms`. Coil is placed perpendicular to the magnetic field. When coil is taken out of the field, `32 mu C` charge flows through it. The intensity of magnetic field will be

One coil of resistance 40 Omega is connected to a galvanometer of 16 Omega resistance . The coil has radius 6mm and turns 100. This coil is placed between the poles of a magnet such that magnetic field is perpendicular to coil. If coil is dragged out then the charge through the galvanometer is 32 muC . The magnetic field is :-

A closed coil consists of 500 turns has area 4 cm^2 and a resistance of 50 Omega . The coil is kept with its plane perpendicular to a uniform magnetic field of 0.2 Wb/m^2 . Calculate the amount charge flowing through the coil if it is rotated through 180^@

A rectangular coil of 25 turns, area of 25 cm^2 and resistance of 4 ohm//turn is placed perpendicular to a varying magnetic field, which changes at the rate of 500 T//s . The induced current in the coil is

A rectangular coil of area 50cm^(2) and 100 turns is placed perpendicular to a magnetic field of 10^(-2)Wb//m^(2) . If the coil is withdrawn from the field in 40 ms, calculate the emf induced.
