Neodymium Iron Boron Magnets, or Rare Earth magnets as they are more commonly known, are an incredibly strong but cost effective product. They offer high magnetic energy and good stability and have become the industry standard when size, strength and efficiency are required.
Some Rare Earth magnets have a dot on one side to differentiate between the sides that attract and repel. If your magnets don’t have this dot, add a dot to each one with a marking pen so you know which side is to be embedded first into the clay.
Magnets are temperature sensitive. When using for polymer clay projects, create your piece with the magnet in place then remove just before baking. Glue the magnet into the piece once all baking is complete. However, Rare Earth Magnets are super strong so he magnetic may still be strong enough after baking. It is up to individual needs.
There are many different ways to make invisible clasps using magnets. YouTube and Pinterest are a good source for ideas. Helen Breil and Melanie Muir are renowned for their use of magnets to create innovative invisible and hidden closures.
