How does a pot magnet differ to a regular magnet?
Magnetism is confined to one face only, where it is concentrated to give the maximum holding force possible for the size of the magnet. They are more resistant to chipping and cracking as they are protected by their steel shell.
Applications
These magnets are versatile magnets which are designed for various industrial applications. The popular industries in which these magnets are used are as follows:
The metal and steel industry
Tool shops
Used to position ferrous-magnetic work pieces
Precautions
The permanent pot magnets must not be exposed to radioactive radiations for longer duration as it might effect their magnetic strength. Φ32mm Powerful Mounting Magnets NdFeB with Internal Thread
This can work within permissible temperature. If these magnets are used beyond permissible temperature limit it might again affect their magnetic strength.
Neodymium pot magnet with a bushing has a protrudent female threaded bushing in the center. It can be used to connect the object with a bolt while the neodymium magnet side is fixed by the attraction force or attract the ferromagnetic object at the neodymium magnet side while the bushing side is fixed onto something with a bolt. ND series pot magnets can also be used as fishing magnets when combined with SC series – screw SC model and SD model together and the rope ties on the space between them.
