ElectromagnetElectromagnet is one of the most important innovations in the history of science and electronics. It has improved the machineries and made many new innovations possible. There are many things that are special about electromagnets. The main features of the electromagnet are

- It is a coil of wire which is in general made of copper.

- It gets its magnetic power because of electrical power. When the current is on the magnetic field generates and when you cut the power off, the magnetic field disappears.

- There are some Electromagnetelectromagnets that can be started and stopped and there are some of them that cannot be stopped.

- It is possible to control the flux density by changing the AC voltage. It is also possible to shape the field and the polarity too.

- With the fluctuation of AC current, the flux density of the magnet will change. The polarity will also change because of this.

- The AC electromagnets can be used to demagnetize the TV screen and all other thing where demagnetization is required.

- In case the current is DC, it works just like general magnet as the current is constant. The magnetic field created in this is just like other magnets.

There are companies which manufacture different kinds of electromagnets that can be used in different machinery and for different operations. They sale it wholesale to reduce cost. The division can be done based on the shape, size and power of the magnet. The strength of the magnet is dependent on the metal, strength of the coil, type of wiring and the power passing through it. When making an electromagnet it is important that you take care of the wire you use and at the same time the length as this would be essential for establishing the connection.
