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.

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.

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 electron beam of velocity v moving in the plane of paper enters a region of uniform magnetic field, which is perpendicular to the plane of the paper and traels in a circular path.Does the kinetic energy of electron change during this time? Give reason.

A circular loop of radius R carrying a current is placed in a uniform magnetic field with its plane perpendicular to B. The force on the loop is

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

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?

An alpha-particle and a proton are moving in the plane of the paper in a region where there is a uniform magnetic field vecB directed normal to the plane of the paper. If the two particles have equal linear momenta, what will be the ratio of their trajectories in the field?

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 loop of iregular shape carrying current is located in an external magnetic field. If the wire is flexible, why does it change to a circular shape?
