The Benefits of Channel Magnets

Channel magnets are standard neodymium countersunk block magnets that are encased in a protective steel housing on the N or S side. Engineered to provide superior sturdiness and impact resistance, this steel housing or channel is also ferromagnetic, thereby incrementally increasing the pull force of the magnet itself.

So, in addition to being exceptionally tough and resilient, neodymium channel magnets also provide a stronger pull force than regular neodymium block magnets of equal N-rating and size. This is because the metal housing focuses the magnetic field in one direction, increasing the magnet's holding power.

For applications that require strength, impact resistance, and lasting durability - all at a lower cost - our channel magnets provide the perfect solution.

Best price I've seen and shipping excellent.

Have been purchasing Neodymium magnets for over 10 yrs now and hanger magnets of the N52 strength are much more expensive from other sites. Seem to be of high quality materials too. The tools I am making with these will be an asset to many field electrical workers and I will post further comments if I can.

These channel magnets are handy. I’m going to mount some in my tool cabinet to hold odd and end tools. I can see many other uses too.
