Sagot :

Answer:

.) An electromagnet may be produced by making electricity flow through a coil of wire wound around an iron nail.

2.) When electricity stops flowing through a coil of wire the nail stops attracting any metal or magnet material.

3.) An electromagnet can be made stronger by using more coils of the wire.

4.) The number of dry cells used affects the magnetism of an electromagnet. More dry cells mean stronger magnetism.

5.) Electromagnets are temporary magnets that can attract any metal or magnetic material.
