Galvanometer: It is a device which shows deflection when the current flows in the circuit. If it does not show any deflection, then it means that the current is not flowing in the circuit.
There is a magnetic field around the current carrying conductor.
It is developed from the observation that the needle of the compass shows deflection near the current carrying wire.
Galvanometer: It consists of compass needle attached to a coil. The coil is allowed to pivot freely in the uniform magnetic field. The magnetic field is created by the poles of the permanent magnet.
In galvanometer,the torque on a current loop in uniform magnetic field is used to measure magnetic field.
An electromagnet of a spring is placed between the poles of a permanent magnet. when there is current in the coil, the resulting magnetic field lines up with the field of the permanent magnet, and indicates the strength of the electric current by deflecting a needle on a dial.<span />
<span>The part of a circuit that increases the electric potential of the electrons is the battery. The correct option among all the options that are given in the question is the third option or the penultimate option. I hope that this is the answer that you were looking for and the answer has actually come to your desired help.</span>
