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

Explain briefly different methods of producing induced electromotive force $(emf)$.

Magnetic field lines of two magnets are shown in figures $A$ and $B$. Select the figure that represents the correct pattern of the field lines. Give reasons for your answer. Also,name the poles of the magnets facing each other.

What is meant by the term "magnetic field lines"? List two properties of magnetic field lines.

If you strike a sharp edge of a metallic knife against the north pole of a bar magnet,it will induce a north pole.

$A$ current-carrying solenoid behaves like a bar magnet.
