History of electricity: A bolt of lightning in the sky Why did it take so long to control electricity? Like other inventions, electricity took thousands of years to develop. For centuries. scientists all over the world investigated first one idea and then another. At first, of course, they didn't even know what they [...]

A magnet holding a steel bar Magnetism is a force created by electricity, or more specifically by electrons. In any iron atom, there are 26 electrons. Each electron has a tiny bit of negative charge. The way these electrons behave is impossible for us to imagine, because it's not like anything we can see. But we can [...]

There are electromagnets inside stereo speakers When did people invent electromagnets? In the early 1800s AD, about 200 years ago, scientists in Denmark and Britain figured out another way to make magnets. (These countries had a lot of scientists thanks to colonization, slavery, and control of trade). History of electricity History of slavery Europe's [...]

You can't see an atom, so you can't see how its protons clump together to make the nucleus. But you can see a similar effect when the force of magnetism (a kind of electricity) works against the force of gravity. All you need is a magnet and a paper clip, a piece of thread and [...]
