To find the direction of the magnetic field around a current-carrying conductor,we use Fleming's left-hand rule.

Identify the type of magnetic fields represented by the magnetic field lines given below and name the type of conductors which can produce them.

Two coils $C_{1}$ and $C_{2}$ are wrapped around a non-conducting cylinder. Coil $C_{1}$ is connected to a battery and a key $K$,and coil $C_{2}$ is connected to a galvanometer $G$. On pressing the key $K$,current starts flowing in the coil $C_{1}$. State your observations in the galvanometer for the following cases:
$(i)$ When key $K$ is pressed on.
$(ii)$ When current in the coil $C_{1}$ is switched off.
$(iii)$ When the current is passed continuously through coil $C_{1}$.
$(iv)$ Name and state the phenomenon responsible for the above observation. Write the name of the rule that is used to determine the direction of the induced current.

All the distribution circuits for domestic purposes are parallel connections.

State the energy change which takes place when a magnet is moved inside a coil having a galvanometer at its ends. Name this phenomenon.

The induced electromotive force $(EMF)$ in a conducting coil does not depend on which of the following?
