Fleming's right-hand rule can be used to find the direction of the magnetic field.

It is established that an electric current through a metallic conductor produces a magnetic field around it. Is there a similar magnetic field produced around a thin beam of moving $(i)$ alpha particles,$(ii)$ neutrons? Justify your answer.

When is the force experienced by a current-carrying conductor placed in a magnetic field the largest?

What is the difference between a direct current and an alternating current? How many times does $AC$ used in India change direction in one second?

Draw a labelled circuit diagram of a simple electric motor and explain its working. In what way are these simple electric motors different from commercial motors?

The following diagram shows two straight wires carrying current. Copy the diagram and draw the pattern of lines of force around them and mark their directions.
