What is Electromagnet?

An electromagnetic is a magnetic that runs in electricity.
People mostly use this in their daily lives and for some kind of
industries in our world. Electromagnetic is one of the most useful things.

Examples of magnetic field.

How does it work?

A magnetic field is produced when there is a flow of moving electrons.

When an electric current is run in a wire, a magnetic force isproduced.

A moving magnetic field going past a wire will induce in it a voltage.

How to make a simple Electromagnetic?

There are so many ways to make an electromagnet. The simple

This is an example of electromagnetic.

one is like this on your side ~>

I will show you how to make the simple way as

shown in the picture above.Materials:- battery
- wire
- nail
- paperclips / stapler

Things to do:
1. Wrap the wire around the nail for about 20 times.
2. Attach the end of the wire to the battery.
3. Your electromagnetic is done!
4. Now try to put the electromagnet on top of the paperclips.
5. You will find out that the paperclips will attach to the electromagnetic that you made.

Example of electromagnet in our lives.

Electromagnet in our daily lives

If you realized it, we use electromagnets often in our daily lives.

Example of them is an ATM machine, when you insert your card,

the machine pulls your card to get inside the machine. This is because

there is a magnetic force in the card, the card was pulled because of

the electromagnetic inside the machine. That is why you can't attach

from one ATM card to another card, if you attached it, there will be no more magnetic force in it.
