Question

Is there any device that produces electricity continuously by the movement of a magnet or coiled conductor? It is such a device that you saw at the beginning of the chapter. Its name is generator. The cycle dynamo is also one such device. We use mechanical energy in generators to move the magnet or coiled conductor continuously. In that case what shall be the energy change in a generator? Mechanical energy → Generator is a device that converts mechanical energy into electrical energy by making use of electromagnetic induction. Generator The following figure will help you to understand the structure of a​

Answer 1

$\huge\fbox\pink{answer}$

The electric dynamo uses rotating coils of wire and magnetic fields to convert mechanical rotation into a pulsing direct electric current through Faraday's law of induction.

Answer 2

Explanation:

A galvanometer is an instrument that can detect and measure small amounts of current in an electrical circuit. ... Essentially, a galvanometer consists of such a needle attached to a coil mounted so that the coil is allowed to pivot freely within a magnetic field created by the poles of one or more permanent magnets.
