Making an Electromagnet

Hi guys

and i am going to make electromagnet

To make an electromagnet, all you need is:

• A piece of wire
• A nail
• A battery
• Some tape

Take the nail

Start winding the nail with wire 20-25 times and leave some space for attaching battery

Use some tape to fix it(as the wire needs to be stuck to the nail)

Attach the battery

verify the electromagnet using iron filling
