Frequently Asked Questions (FAQs)

1. What does N48 magnet mean?

What does the N35, N40, N42, N45, N48, N50, N52 grade mean? Neodymium magnets are graded by the maximum strength they can be magnetized to. The higher the number the stronger the magnet is, however the higher the number the more brittle the magnet becomes as well.

2. What are the strongest commercial magnets?

Neodymium magnets, or rare earth magnets, are known to be the most powerful type of permanent magnets available to consumers today.

3. Are there magnets stronger than N52?

You can get the same strength as an N52 magnet by using a slightly larger N42 magnet. If you have slightly elevated temperatures, in the 140°F to 176°F range (60°C -80°C), N42 magnets might actually be stronger than N52.
