What is a rare earth magnet grade?

When it comes to rare earth magnets, the grade is everything. It tells you about the magnet's maximum energy product, which basically describes how much magnetic energy is stored within. Grades typically range from N35 to N52 – higher numbers signify stronger magnets.

Are rare earth magnets corrosion resistant?

Coating and Corrosion Resistance The majority of rare earth magnets are susceptible to corrosion, therefore most are coated to prevent such deterioration. Common coatings include nickel, copper, zinc, or epoxy.

🏅 Most Powerful Rare Earth Magnets

Q: Are rare earth magnets strong?

1.) Magnet Strength and Grade Rare earth magnets, particularly neodymium magnets, come in various strengths and grades which are designated by an 'N' rating (e.g., N35, N52). Higher ratings indicate stronger magnets, with N52 being one of the strongest commercially available.

Q: How do I choose a rare earth magnet?

When purchasing rare earth magnets, it's important to determine the required strength for your application. Overly powerful magnets may be dangerous or could damage sensitive materials, while those not strong enough could prove ineffective. 2.) Size and Shape Considerations
