Frequently Asked Questions (FAQs)

1. What is a ring magnet?

A thin flat circular magnet where the thickness does not exceed the diameter and there is a hole through the center. Ring magnets are commonly used when a mechanical attachment method is needed to secure the magnet. We carry both straight sided and countersunk magnets.

2. What is the use of ring magnet?

Ring magnets are usually used in science experiments such as a demonstration of magnetic repulsion where the magnetic rings are threaded through a wooden pole. When the same poles of the magnets face each other they won't touch. Ring magnets are also occasionally used in medicine.

3. Are ring magnets strong?

Neodymium ring magnets are strong Rare-Earth magnets, circular in shape with a hollow center. Neodymium (also known as “Neo”, “NdFeb” or “NIB”) ring magnets are the most powerful magnets commercially available today with magnetic properties that far exceed those of other permanent magnet materials.

4. Does a ring stick to a magnet?

All aren't attracted to magnets. Most gold used in jewelry is actually a mix of silver and gold. Like gold, silver isn't attracted to a magnet. There may even be other metals like copper, platinum, or nickel mixed with the gold to give it different colors.
