Moving Charges ...

Under the influence of a uniform magnetic field a charged particle is moving in a circle of radius R with constant speed V. The time period of the motion

An alternating electric field, of frequency v, is applied across the dees (radius = R) of a cyclotron that is being used to accelerate protons (mass = m). The operating magnetic field (B) used in the cyclotron and the kinetic energy (K) of the proton beam, produced by it, are given by

A rectangular loop carrying a current i is situated near a long straight wire such that the wire is parallel to the one of the sides of the loop and is in the plane of the loop. If a steady current I is established in wire as shown in figure, the loop will

A circular coil of 20 turns and radius 10 cm is placed in uniform magnetic field of 0.10 T normal to the plane of the coil. If the current in coil is 5 A, then the torque acting on the coil will be

A 100 turns coil shown in figure carries a current of 2 amp in a magnetic field B = 0.2 Wb/m². The torque acting on the coil is

Two thin, long, parallel wires, separated by a distance ‘d\' carry a current of ‘i\' A in the same direction. They will

The relation between voltage sensitivity (σ_V) and current sensitivity (σ_i) of a moving coil galvanometer is (Resistance of galvanometer = G)

Three long straight wires A, B and C are carrying current as shown in the figure. Then the resultant force on B is directed
