How are magnets made?
Answers
Answer:
One method is to make a magnet out of a mixture of different types of metal. The metal is heated and melted, then placed in a cast, or container that's used to make a shape. The metal cools in the cast. Then magnetism is added to it, usually with a powerful electromagnet that's been magnetized by an electrical current.

What Are Magnets?
What can move metal objects and even make them dangle in the air without touching them? Magnets! You have probably had fun moving paper clips or nails around with a magnet and were excited because it seemed like magic, but there's actually a scientific explanation for how this works.
Magnets are materials that can attract or pull objects towards them. Lodestone is a type of rock that is a natural magnet on Earth. When you put it in a compass, lodestone naturally makes the compass point north and south because of the earth's magnetic field, or invisible force that pulls magnetic objects on the Earth. If you rub lodestone on other metals, like iron or steel, it can transfer its magnetism (or magnetic power) to those metals.
Magnets are made of different metals.

How Were Magnets Made Long Ago?
Long ago, people dug up lodestone and used it as a natural magnet. If they needed to create other kinds of magnets, they'd just rub it on some of those other metals. This is a simpler way to make magnets that we can still use, but we've also developed a lot of other magnet making strategies. Let's take a closer look at the more complex way that magnets are made today.
