Respuesta :
To creat an electromagnet, we need power source, metallic core and electrical conductor.
To find the correct optio among all the options, we need to know about electromagnet.
What is electromagnet?
- Electromagnet is a temporary magnet.
- An electromagnet is used wherever controllable magnets are required.
What does an electromagnet consist?
It consists a core of magnetic material surrounded by a coil of metallic conductor through which an electric current is passed to magnetize the core.
Thus, we can conclude that to make an electromagnet, we need power source, metallic core and electrical conductor.
