The closed loop PQRS is moving into a uniform magnetic field acting at right angles to the plane of the paper as shown in Fig 6.50 state the direction in which the induced current flows in the loop.

An irregular shaped with PQRS placed in uniform magnetic filed perpendicular to the plane of the paper changes into a circular shape. State, which reason, the direction of the induced current iin the loop.

An irregular shaped wire PQRS shown in the figure. placed in a uniform magnetic field perpendicular to the plane of the paper changes into a circular shape. Show with reason the direction of the induced current in the loop.

The current flows form A and B as shown in the figure. The direction of the indueced current in the loop is

A current through a wire PQ is increasing. In which direction the induced current flows in the closed loop?

Fig. below shows planer loops of different shapes moving out or into a region of magnetic field, which is directed normal to the plane of the loop and away from the reader. Determine the direction of induced current. in each loop using Lenz's law.

A square current carrying loop is suspended in a uniform magnetic field acting perpendicular to the plane of the loop. If the force on one arm of the loop is vec(F) , the net force on the remaining three arms of the loop is

The figure shows certain wire segments joined together to form a coplanar loop. The loop is placed in a perpendicular magnetic field in the direction going into the plane of the figure. The magnitude of the field increases with time I_(1) and I_(2) are the currents in the segments ab and cd. Then,

A current carrying loop is placed in uniform magnetic field. The torque acting on it does not depend upon

A particle with charge q moving with a velocity v in the plane of the paper enters a uniform magnetc field B, acting perpendicular to the plane of the paper. Deduce an expression for the tie period of the charge, as it moves in a circular path in the field. Why does the kinetic energy of the charge not change, while moving in the magnetic field?

A metallic square loop ABCD is moving in its own plane with velocity v in a uniform magnetic field perpendicular to its plane as shown in the figure. An electric field is induced.
