  • Consider "Pot" type in various sizes, especially if the steel is thin - they are cheaper

  • This type of magnet never weakens with age
  • Triple plated for durability: Ni/Cu/Ni

Potential Uses:

  • Attaching items eg panels/fittings/tools firmly to steel
  • Heavy door/gate closures onto steel
  • Also to hold gates open
  • Picking up nails off factory floors
  • Retrieving lost steel items
  • "Fishing" for steel items

Warnings:

  • Not for kids! Two or more, if swallowed, can lethally puncture gut tissue.
  • They can pinch skin and cut clothing.
  • The material is brittle. It can chip or break during collisions. Eye protection advised.
  • For credit cards, pacemakers etc, keep at a distance where the field is negligible.
