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

For a current in a long straight solenoid,$N-$ and $S-$ poles are created at the two ends. Among the following statements,the incorrect statement is:

If the direction of current is reversed,the direction of magnetic field is also reversed.

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?

$A$ coil of insulated wire is connected to a galvanometer. Explain what happens if a bar magnet with its north pole towards one face of the coil is:
$(i)$ moved quickly towards the coil,
$(ii)$ kept stationary inside the coil,and
$(iii)$ moved quickly away from the coil?

Whose magnetic field is like a magnetic field of a bar magnet?
