Round and Rectangular Electromagnets

Round and Rectangular Flat-Faced Electromagnets are available in a variety of sizes. Flat-Faced magnets should only be used on flat, smooth material where the entire magnet face is in contact. They can be used in manually operated or automated applications.

Magnets listed utilize 12 volt D.C. current (24VDC and 110VDC are available by request).
Standard Leads are 24″
Dimensions are in inches
Pounds pull ratings are maximum on low carbon steel at magnetic saturation.

An electromagnet is a kind of magnet whose magnetic field is created by the flow of electric current. The magnetic field disappears when the current stops.Electromagnets offer the advantages of controlled holding power and on command release. Through the application of controlled DC electrical current, an electromagnet has the ability to attract and hold ferrous materials with varying degrees of force, and to release the item as required.

MPCO supplies electromagnets in a variety of sizes, shapes and current strengths to meet your end-use requirements. Our technical sales team will work with you to determine what type of electromagnet will best suit your purpose.

Adams’electromagnets are available in flat-faced round and rectangle form or bi-polar rectangle.

Permanent Magnets vs. Electromagnets
The strength, ability and versatility of electromagnets have rapidly evolved over the past few decades. Electromagnets are a significant element in several industrial processes, and have played a leading role in the development of the assembly line in modern factories. Electromagnets are used in many electric device applications, including:

Electric bells
Industrial lifting magnets
Magnetic locks
Magnetic recording and data storage equipment
Magnetic separation of materials
Motors and generators

The magnetic field of bi-polar electromagnets has a greater “reach” than that of flat-faced electromagnets. Subsequently, they perform better than equivalent flat-face magnets when operating through an air gap or any type of non-magnetic material between the workpiece and the electromagnet. Bi-polars, due to their extended poles, are designed to handle round parts, parts with uneven surfaces, and odd shaped parts. Contoured, auxiliary pole shoes can be added for better contact with the workpiece.

Effect of an Air Gap
An Air Gap can be the result of the actual distance from the workpiece, or a gap created by a non-ferrous material. The chart below compares the effect of an air gap on a flat-faced electromagnet compared to a similar size bi-polar electromagnet.

Electromagnets require direct current power in order to generate a magnetic field. Typically the applied voltage is Direct Current (DC), but in some cases, Alternating Current (AC) can be used. Variable power sources and remote control are available. Smaller magnets can operate on 12 volts DC; larger magnets may require 115 or 220 VDC. A rectifier is required to release the electromagnet from the surface on which it is applied. The rectifier can be mounted on the magnet, and be operated by remote control.

Whether used in manual or automated handling of ferrous parts, they must release the work as readily as they attract and hold. Release is a function of the rectifier and not the magnet. Most rectifiers incorporate a provision for reverse current that ensures positive release of even those alloy steels which are magnetically retentive. Variable power and remote control are available.
