A magnetic dipole is under the influence of two magnetic fields. The angle between the field directions is 60°, and one of the fields has a magnitude of `1.2 xx 10^(-2) T.` If the dipole comes to stable equilibrium at an angle of 15° with this field, what is the magnitude of the other field?

Give definition of 1 T magnetic field.

The splitting of the spectral lines under the influence of magnetic field is called …….

Why don.t two magnetic field lines intersect each other ?

(1) Define magnetic field . (2) What are magnetic field lines ?

An electric dipole is placed at an angle of 30^@ to a non-uniform electric field. The dipole will experience

A 100 turn closely wound circular coil of radius 10 cm carries a current of 3.2 A. (a) What is the field at the centre of the coil? (b) What is the magnetic moment of this coil? The coil is placed in a vertical plane and is free to rotate about a horizontal axis which coincides with its diameter. A uniform magnetic field of 2T in the horizontal direction exists such that initially the axis of the coil is in the direction of the field. The coil rotates through an angle of 90^@ under the influence of the magnetic field. (c) What are the magnitudes of the torques on the coil in the initial and final position? (d) What is the angular speed acquired by the coil when it has rotated by 90^@ ? The moment of inertia of the coil is 0.1 kg m^2 .
