In order to find the force experienced by a current-carrying conductor,we can use Maxwell's corkscrew rule.

Describe an experiment to demonstrate the force acting on a current-carrying conductor placed in a magnetic field.

State the condition for electromagnetic induction to take place. $A$ cylindrical bar magnet is kept along the axis of a circular coil as shown in the figure. Will there be a current induced in the coil if the magnet is rotated about its axis? Discuss.

$A$ magnetic compass shows a deflection when placed near a current-carrying wire. How will the deflection of the compass be affected if the current in the wire is increased? Support your answer with a reason.

By placing an iron-like metal inside the solenoid,its magnetic field becomes $......$

In the diagrams shown below:
$(i)$ Name the type of current in two cases.
$(ii)$ Identify any one source for each type of these currents.
$(iii)$ What is the frequency of current in case $(ii)$ in India?
$(iv)$ Use above graphs to write two differences between the current in two cases.
