Frequently Asked Questions (FAQs)

1. Which is stronger N42 or N52 magnet?

N50 and N52 magnets may be stronger, but their maximum working temperature is limited to 60 ℃, or 140°F. Comparatively, N42 neodymium magnets have a maximum working temperature of 80 ℃, or 176°F. This makes them a better choice for applications where higher working temperatures are involved.

2. What does grade N42 magnet mean?

The grade N42 means a neodymium magnet has a maximum energy product of 42 MGOe. It refers to the maximum magnetic energy that the material can be stored. It can be showed by the magnet's Demagnetization Curve, or BH Curve – the strongest point is (BH)max.
