The working principle of the electromagnet

- Nov 21, 2017 -

Electromagnets are more common in our daily life, the frequency of use is also high, then you know how our electromagnet work? Here we talk about his working principle:

The so-called electromagnet, is energized to produce magnetic, like magnets can absorb iron objects. Electromagnets can be used in a variety of areas, such as large-scale amusement equipment, automotive, aerospace, industrial, and other undertakings(Neodymium Disc Rare Earth Magnets). Common electromagnet applications such as: punch card to work clock, supermarket cash register, access to some units of automatic doors. These electromagnets through the electric energy is converted to a magnetic field, then the magnetic field generated by the magnetic force acting on the center of the iron core, the core action.


Super Strong Neodymium Magnets Disc

The main application of the electromagnet is the force generated by the core action. This strength can do a few grams a few grams, in theory can be infinite, basically to be able to do a few hundred kilograms on the same. The magnetic effect of current is evidence of the presence of a magnetic field around the current. When the electromagnet is energized, a current flows through the coil to generate a magnetic field, so that the magnetic field acts on the iron core to generate an action.
