Topic: the magnets.

Objective: to know what is the importance of the magnets.

One of the main practical uses of magnets is in the production of electricity. Just as electricity can create magnetism in an electromagnet, the movement of magnets in a generator can produce electricity. Magnets are also used for certain high-speed trains, computers, telephones, factory machines and compasses.

Maxwell showed mathematically how a changing magnetic field creates a changing electric field (and vice versa). Therefore, magnetism is very important because we use it to create electrical energy. In fact, most of the energy that we use today comes from rotating magnets (see below).

Magnets are used to make a tight seal on the doors to refrigerators and freezers. They power speakers in stereos, earphones, and televisions. Magnets are used to store data in computers, and are important in scanning machines called MRIs (magnetic resonance imagers), which doctors use to look inside people's bodies.

speakers have magnets in them, Electric motors use magnets, Microphones use magnets, There are magnetic chucks to hold things, Lifting magnets for moving around scrap metal, Toy magnets for art projects, Robots with magnetic feet for walking up walls or ship hulls, magnetic compass to guide you, Magnets in ...

magnetism can produce electromagnetic field that can create power or electricity. 4. It promotes health benefits to reduce pain and stress. It also provides energy and better blood circulation.
