Hi everybody! Today I’d like to tell you how to make a simple electric magnet.
May be somebody already know that, or studied at physics or crafts lessons. Well, let’s start. I’m going to show it for those who do not know it yet. We need a copper wire, an electrical tape, AA battery, a nail, scissors, there are pins in the box for testing.
First, we have to wrap a copper wire around the nail.
It looks like that. It’s necessary that coils are tight. Cut off the odds and strip the isolation.
Then, connect the terminals. Cut a piece of electrical tape. Connect one terminal to the minus, and the second one connect to the plus. We have got such an electric magnet. Let’s check it.
