6. Electromagnetism is the study of electromagnetic force
7. Electricity and magnets are closely related to each other.
8. Electricity can produce magnets while magnets can produce electricity.
9. A magnet is usually made of iron.
10. Magnets can attract objects such as wood, paper, and other materials made of plastic.
11.The number of dry cells also affects the strength of electromagnet.
12 Less dry cells mean more electrons flowing in the electromagnet and, therefore, stronger
magnetism is produced.
13. Magnets in different industries and businesses are usually used in electromagnet-powered
devices such as cranes, cutters, fax machines, computers, etc.
14. Powerful cranes use electromagnets to move scrap iron and steel or separate metals for
recycling. Generators in power plants rely on magnets like the ones found in electric motors to produce
electricity. Transformers, devices that use electromagnets to change high-voltage electricity to low-voltage
electricity or vice versa, are often used at homes and in offices.​
