Description

Product information

The Polymag is a large horseshoe type permanent magnet completely encapsulated in a polymer coating to significantly reduce the risk of breakages, abrasion damage and corrosion. Permanent magnets by their nature are inherently brittle and susceptible to impact damage. This design makes the Polymag more robust and long lasting. The Polymag is coated in a tough non-brittle polymer which will not crack and is resistant to impact damage, abrasion and most chemicals. The integral heavy-duty handle enables easy removal from the work piece.

Permanent magnets

Permanent magnets are sometimes used for magnetic particle inspection as the source of magnetism. The two primary types of permanent magnets are bar magnets and horseshoe (yoke) magnets. These industrial magnets are usually very strong and may require significant strength to remove them from a piece of metal.

Some permanent magnets require over 50 pounds of force to remove them from the surface. Because it is difficult to remove the magnets from the component being inspected, and sometimes difficult and dangerous to place the magnets, their use is not particularly popular.

However, permanent magnets are sometimes used by divers for inspection in underwater environments or other areas, such as explosive environments, where electromagnets cannot be used. Permanent magnets can also be made small enough to fit into tight areas where electromagnets might not fit.
