What are electromagnet of daily use

The use of electromagnet right under the broad terms the electromagnet used in daily life.

From which can be found that the strength of the magnetic force is larger for large current. 2. The selected fixed voltage first, then answer the medium line 80 turn; Medium line 140 turn; Medium line 200 turn three pieces of electromagnet and dynamometer, respectively, measure and record the magnetic intrusive, it can be found that the more coil number of turns the stronger the magnetism (1) the use of electromagnet right under the broad terms the electromagnet used in daily life.

Also is to install the magnet on the crane, after electrify suck up a lot of steel, after moving to another location after block current, then put down steel. The oil in general large electromagnetic crane can lift a few tons of steel. 2. The electromagnetic relay is controlled by electromagnet switch automatically. The use of electromagnetic relay can control with low voltage and low current, high voltage and strong current and complete operation over a long distance. 3. The bell is also often used, closed circuit, electromagnet will attract the elastic piece, and then make the hammer to the direction of iron bell, so that the hammer impact iron bell and announce voice, together with the circuit disconnect, electromagnet, no magnetic, so the hammer was bounced, closed circuit. A repetition of such, bell will keep on ringing announced. 4. Electromagnetic separator is based on the principle of magnet can attract iron ore. When electromagnetic separator in homework, iron ore B will fall into the box. Ore in the process of falling, then through the electromagnet not iron ore cannot be electromagnet attraction, but due to the effect of gravity directly into A box; The iron ore is attracted by electromagnet, adsorption and roller in the roller rolling together, the B box above electromagnet attraction in the ore is very small, so the ore will fall into the box B due to the effect of gravity. 5. Maglev train is made without touching the electromagnetic suspension, guidance and drive system of the high-speed magnetic levitation train system. Its speed is fast, appropriate can reach more than 500 kilometers, has a high speed, low energy consumption operation low noise, strong climbing ability, safe and comfortable, not fuel, less pollution and so on merits. Of the elevated method, it is still choose and takes up little plough.
