ELECTROMAGNETISM
You might not think magnets and electricity are related. After all, they do different things! But magnets and electricity have many similarities. And they happen to be very closely connected. It’s fun to play with magnets. You can make them pick up things or stick to certain objects. And if you put two magnets close together, sometimes they stick to each other and sometimes they push away, or repel, each other, depending on their positions. Sounds a lot like objects with an electric charge, right?
