A metallic wire coil is stationary in a uniform magnetic field. What is the e.m.f .induced in the coil?

What is induced e.m.f.?

To induce an e.m.f. in the coil

A coil of dimensions 30 cm xx 20 cm is kept such that its plane is at right angles to the direction of uniform magnetic field of value 0.08 Wb/m^2 . Calculate the e.m.f . induced in the coil, If the value of field is reduced to 25 percent of the original value in 0.6 second.

A rod of length l is rotated about its one end, perpendicular to a magnetic field of induction B What is the e.m.f induced in the rod

What is the basic cause of induced e.m.f.?

The maximum value of e.m.f.induced in a coil rotating in a uniform magnetic field is called as

A current i flows in a circular coil of radius r . If the coil is placed in a uniform magnetic field B with its plane parallel to the field, magnitude of the torque that acts on the coil is

The magnetic field at the centre of the current carrying coil

A square coil of side 10 cm consists of 20 turns and carries a current of 12A. The coil is suspended vertically and the normal to the plane of the coil makes an angle of 30^@ with the direction of a uniform horizontal magnetic field 0.8 T. What is the magnitude of torque experienced by the coil?

A rectangular coil (0.5 m xx 0.4m) has a resistance of 5Omega . The coil is placed in a uniform magnetic induction of 0.05 T perpendicular to the place of the coil. If the magnetic induction is uniformly reduced to zero in 5 xx 10^-3s , find the current induced in the coil
