attracted by it. Repeat the experiment by using battery of 3 and 4 cells also.

(i) Mention two ways by which you can increase the magnetic field produce by an electromagnet .

(ii) Write two use of electromagnets .

(iii) How are electromagnets prepared​

Answer 1

Answer:

A terminal is the point at which a conductor from a component, device or network comes to an end. Terminal may also refer to an electrical connector at this endpoint, acting as the reusable interface to a conductor and creating a point where external circuits can be connected.
