An electron beam enters a magnetic field at right angles to it as shown in the Figure.

The direction of force acting on the electron beam will be:

What are the special features of commercial electric motors?

In an electric motor, the direction of current in the coil changes once in each:

The force experienced by a current-carrying conductor placed in a magnetic field is the largest when the angle between the conductor and the magnetic field is:

The force exerted on a current-carrying wire placed in a magnetic field is zero when the angle between the wire and the direction of magnetic field is:
