Electromagnets

Electromagnets In our store are available a wide range of electromagnets. Systems using electrically magnets can attract, repel or otherwise move or lift objects made of ferromagnetic metals such as iron, less cobalt or Nickel. The electromagnets holding and pushing are available in a wide power range and intensity of workthat allows you to choose them for a variety of electronic devices and specific purposes.

Powered by an electric current magnets for mechanical systems

Magnet is a type of magnet in which a magnetic field is generated by electric current. Electromagnets usually consist of a wire nawiniętego the coil. The current flowing through the coil creates a magnetic field that is concentrated in the middle of the coil. The magnetic field disappears after switching off the current. Windings of wire, often wound around a magnetic core made of a material ferromagnetycznego, such as iron core concentrates the magnetic flux and creates a stronger magnet.

Easy control by magnetic field

The main advantage of an electromagnet over a permanent magnet is that the magnetic field can be quickly changed by controlling the amount of electric current in the coil. However, unlike a permanent magnet that requires no power, an electromagnet requires a constant power source to maintain the magnetic field. Our online store offers the electromagnets supply the different voltage and receiving different current, which allows you to configure systems to individual needs. There are also modules are integrated with control electronics that simplifies the implementation of such a solenoid in an electronic system, for example, with the Arduino module.

The electromagnets used for access control

One of the uses of electromagnets holding available in our product range are access control system - locks for doors. The magnets holding are used for fastening doors, which at the moment should not be opened. The electronic system, after receiving a signal from a system controlling the lock - reader cards, RFID token, code keyboard, etc. - deenergetyzuje the coil of the electromagnet that it ceases to attract to the metal plate on the door. At this point, the door can be normally open and enter the room. The magnet will, after some time, re-attached and at the moment of closing the door, can not open them, to re-signal with the access control system. Electromagnets can test yourself in many electronic projects.
