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.

Magnet Safety Warning

Please use extreme caution when handling these block magnets. They are incredibly strong and powerful, and can pose a serious risk to your safety.

These large, grade N52 block magnets are very difficult to separate and can snap back together with incredible speed and force. This may cause them to break and send small fragments flying into the air, potentially causing injury.

With 65 lbs of pull force, these block magnets can also severely pinch your fingers if they snap back together. For your safety, keep these strong magnets far apart and at a safe distance of several feet or more once separated. Hand and eye protection is strongly recommended when handling these magnets.

Utilitie truck doors

I use them to hold the metal doors to my utility truck. It had pumps that would push the doors open when I made a turn if I forgot to lock them they fit perfect to the door edge
And would hold the door closed if I didn’t lock it. No more losing equipment. Thank you.

Absolutely perfect for my need!

I’ve tried a bunch of rare earth magnets for my custom magnetic knife holder designs, none have fit the bill nor have had a decent pull strength to hold heavier culinary knives. These by far have worked out incredibly well. Will be ordering many more. I highly recommend them. Plus they are a good price point. Attached is a sample, now I can refine my designs w/ more beautiful wood species.

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.
