Measurements:

Despite they have a steel pot but this also does not provide any protection against flowing of magnetic force out. Thus while making pot magnet the distance between the steel element and the magnet should be maintained.

Applications
Samarium Cobalt Pot Magnets The samarium pot magnets have following applications:
•Welding moulds of spot-welding machines
•In very small tools
• In various gripping operations
