Strong Channel Magnets

What are channel magnets?

Channel magnets are standard countersunk neodymium block magnets with the N or S surface encased in a metal shell or channel made of ferromagnetic steel. This protective steel channel dramatically increases the sturdiness and impact resistance of the magnet - while also increasing the strength or pull force of the magnet itself at the same time. As a result, channel magnets deliver increased value by providing added pull force at a lower cost.

Commonly used for holding, mounting, and positioning applications - channel magnets are also utilized to hold metal objects in place, such as doors, windows, and cabinets. They are also widely used for attaching signs, lights, shelves, artwork, and other fixtures to metal surfaces. Plus, channel magnets are also typically found in most forms of machinery, as they can hold metal parts in place during the manufacturing process.

What makes channel magnets so strong?

Channel magnets offer a great value due to their ability to amplify an individual magnet's strength. The channel itself is made of ferromagnetic steel, which means it can be magnetized by induction and develops its own magnetic field. This additional magnetic surface adds to the overall pull force of the magnet - making the magnet stronger than it would be without the steel cup.

This is why steel is often used in the construction of magnets, such as in the housing of channel and pot or cup magnets. It makes the magnet more effective at attracting and holding other ferromagnetic materials - as well as providing added value for an improved bottom line.
