You can do a lot of work with its magnetism:

1. Sort, make magnetic selection in iron essence powder and iron ore

2. Magnetic control, switch control in the electronics field, such as magnetic control tubes, sannantic tube

3. Magnetic therapy, magnetic therapy in the field of medicine

4. Electromagnetic conversion, belong to the basic application, transformers, speakers

5. Guide, Guide Needle

6. Magneto, electromagnetic interference in the field of military radio

A special "magnet", the superconducting expert of the Cambridge Engineering Department, Tim Coombs, developed a super magnet, which is a new type of magnet that is 10 times greater than the conventional magnetic field. A one -inch diameter super magnet is enough to suck new technologies of seven tons of trucks. Dr. Tim CoomBS said: "By making the magnet smaller and more powerful, we give a new character to the magnet." In the process of the formation of the super magnet, we used an electromagnetic wave that transformed the thermal energy into a ready -made thousands of ampels. The series of electromagnetic waves formed by the heat instrument will magnetize the superconductors. Just as the nails can be magnetized by touching the magnetic block, as long as the liquid nitrogen is used to keep the superconducting low temperature, the electromagnetic wave will continue to generate a powerful and stable magnetic field. Then, a small magnet can be placed in the palm of the palm but it can provide a powerful magnet that can provide a cruise power.
