Question

Identify the materials necessary to create an electromagnet.

A: Power source, metallic core, and electrical conductor.

B: Electrical conductor and power source only.

C: Metallic core, magnet, and power source.

D: Metallic core and power source only.

I Appreciate it.

Answer 1

the answer is A :)
you can orove it at home by wrapping a copper wire (or any wire that conducts electricity) around a nail many times and touching one end of the wite to each terminal of a battery. (warning: it gets hot)

Answer 2

Answer: The correct answer is "Power source, metallic core, and electrical conductor".

Step-by-step explanation:

Electromagnet: It is a temporary magnet. It consists of wrapping coils around iron core and the power source. When the current passes through the coils around the iron core then it will get magnetized. The domains of the electromagnet gets aligned.

As long as the current passes through it, it will get magnetized. It will loose its magnetism easily when the power is switched off.

In the electromagnet, the strength of the magnetism can be increased or decreased. The poles of the electromagnet are not fixed.

Therefore, the correct option is (A).
