Flat magnetic loop manufacturers introduced magnet type:

Magnetic loop manufacturers flat permanent magnet at the work site will be introduced using control handles connect and disconnect. They can be used to carry either flat materials, can also carry less than 2,200 pounds of round parts. These lifting devices as ' self-contained ', septum magnet within a machine shop can be moved to a different place of work, but a drawback is the limited lifting capacity of permanent magnets.

Flat magnetic loop manufacturers introduced electric excitation and electric magnet material into the magnet on the surface. Power on the electromagnet wound around an iron core coil, the iron particles in the material arranged in a common direction, magnet creates a magnetic field. General DC solenoid works, so you need rectifier. Is different from permanent magnets, electromagnets require a constant power source, that may use of electromagnets instead of being seen as a shortcoming, is seen as an advantage. When you are using electromagnets, power failure could be catastrophic, although you can use many available on the market today use power and battery backup systems to address these problems. The other hand, compared with permanent magnets, electromagnets can change the power current capacity to provide users with greater flexibility.
