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.

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.

Assuming that the earth's magnetic field is due to large circular loop of current in the interior of the earth, what is the plane of the loop and what is the direction of current around it?

Figure shows three different orientations of a circular coil rotating in the magnetic field between the poles of a horse shoe magnet. Determine the direction of induced current in the coil, if the rotation is anticlockwise as viewed by the reader.

Current loop does not tend to rotate when its plane is bot to the direction of magnetic field. Why?

A rectangular wire loop of sides 8 cm and 2 cm with a small cut is moving out of a region of uniform magnetic field of magnitude 0.3 T directed normal to the loop. What is the emf developed across the cut if the velociy of the loop is 1 cm s^-1 in a direction normal to the: longer side of the loop? for how long does the induced voltage last in each case?

An electron moves along the line AB, which lies in the same lane as a circular loop of conducting wires. What will be the direction of the current induced in the loop, if any?

A rectangular wire loop of sides 8 cm and 2 cm with a small cut is moving out of a region of uniform magnetic field of magnitude 0.3T directed normal to the loop. What is the emf developed across the cut if the velocity of the loop is 1 cm s^-1 in a direction normal to the shorter side of the loop? For how long does the induced voltage last ?
