Electromagnets provide an efficient and economical solution for handling and holding parts. Electromagnets are available in a number of shapes and sizes. Bunting® Electromagnets require little maintenance and can be used in a variety of manual and automated applications.

How Electromagnets Work


Electromagnets are a combination of electricity and magnetism. In an electromagnet, the magnetic field is produced by an electric current and disappears when the magnet is turned off. Through controlled use of electricity, the electromagnet can attract and hold heavy iron, scrap steel and other ferrous materials. The primary benefit of an electromagnet over a standard magnet is that the strength can be controlled. Our line of electromagnets will safely pick-up and move your material:
  • Flat-Faced Round and Rectangular Electromagnets
  • Small Bi-Polar Electromagnets
  • Low Profile Electromagnets
  • Round Lifting Electromagnets

Why power supplies are crucial to the functioning of electromagnets


Note – a power supply is needed to operate and release the item as required. Electromagnets must be able to release ferrous object as readily as they attract and hold them. Release is the function of the power supply – not the magnet. Power supplies render a reverse current that ensures positive release of even those alloy steels that retain induced magnetism extremely well. All Bunting Power Supplies are designed to provide D.C. power for industrial electromagnets.

BPSE Power Supplies are ideal for robotics or “pick and place” applications.

BPS1 Power Supplies


These feature a 3-position manual control switch for on-off-release, an indicator light, 6’ input cord with plug, 3’ output cord, and a splash-resistant enclosure.

BPS3 Power Supplies


These cycle and release rapidly and cleanly, making them excellent for high-speed automated processes. An SPST switch, limit switch, or PLC output may be used to operate the Power Supply. The release cycle is completely automatic, so operator judgement is not required even with manual switches. An adjustable timed pulse of reverse current to the magnet effectively releases the load.
