Electromagnets...electromagnets are magnets attract, or pull, some kinds of metal objects. Stronger magnets exert a greater pull on the objects they attract. Sometimes it would be useful if you could turn off a magnet when you did not want it to attract objects. That is what an electromagnet can do. Some electromagnets .in power plants and factories electromagnets are very large. You can make a small, simple electromagnet in school or at home.
