A magnet keeper is a bar made from iron or steel. They are placed across the poles of a permanent magnet to help preserve the strength and close the magnetic circuit, which stops any external metal from being attracted to the magnet.
We use them as a safety function for when we send out our magnets in the post.
Due to keepers being used to closing a circuit they can be fiddly to remove, with this in mind we have created some videos to show you how to remove them safely.
Small Magnets
Here demonstrates how to remove a keeper from a smaller-sized magnet.
Large Magnets
Next, we have demonstrated how to remove a keeper from a larger magnet.
Strong Magnets
Finally, we wanted to demonstrate how to remove a keeper from one of our stronger magnets.
