Round Base Magnetsprovide exceptional economy, high holding power and compact designs.
The addition of a metal cup to a standard, inexpensive, cylindrical Ceramic Magnet provides a platform for a number of design applications. Several standard sizes are available, and all have a hole in the magnet and the metal cup to accept a handle or other device.

Electro Magnets run a current through wire coiled around an iron core to create a magnetic field. The strength of the field is related to the size of the coil/core and the amount of current passing through the wire. An advantage of this configuration is that the magnetic field disappears when current is removed. Contact Rochester Magnet for technical assistance in understanding how an Electro-Magnet can solve your design challenge.

Channel Magnets multiply the attractive force of your magnet by placing it into a metal channel.
This configuration is popular for knife holders, tool holders and similar devices due to the simplicity. Another benefit is the ability to create a large, highly attractive surface using simple, inexpensive components.

Ceramic Holding Assemblies resist demagnetization by vibration and electrical fields. They are ideal for use as work holders on welding machines and other equipment with strong demagnetizing fields.
Cylindrical Ceramic holding assemblies can be installed by a simple press fit with only a slight reduction in holding values.

Sandwich Magnets are comprised of two peices of ferrous metal with a magnet in between. The presence of the metal increases the attractive force manyfold.
This configuration is frequently used in latches and other things like that...

Shielded Magnets are primarily used to supply a holding force in limited areas of Steel tools, dies and fixtures. The sheath, acting as an insulator, prevents undue loss of magnetic flux at the magnet pole when inserted directly into Steel components. This type of assembly is usually efficient when there is no severe limitation upon magnet length. The pull force against a flat Steel surface will vary from several ounces to pounds, depending upon magnet diameter and length. Greatest pull is achieved if magnet length is at least 4.2 times the diameter - less pull when length of magnet is reduced.
