FAQ

1. What is Neodymium?

Neodymium (Nd) is a rare earth element with an atomic weight of 60, typically found in the lanthanide section of the periodic table.

2. What are Neodymium Magnets and How Are They Made?

Neodymium magnets, also known as Neo, NIB, or NdFeB magnets, are the most powerful permanent magnets. Composed of Neodymium Iron and Boron, they exhibit exceptional magnetic strength.

3. How Do Neodymium Magnets Compare to Others?

Neodymium magnets are significantly stronger than ceramic or ferrite magnets, boasting about 10 times the strength.

4. What Does the Magnet Grade Mean?

Different grades of Neodymium magnets balance material capabilities and energy output. Grades impact thermal performance and maximum energy product.

5. Do Neodymium Magnets Require a Keeper?

No, Neodymium magnets maintain their strength without a keeper, ensuring long-lasting performance.

6. How Can I Identify Magnet Poles?

Poles can be identified using a compass, gauss meter, or another magnet's identified pole.

7. Are the Two Poles Equally Strong?

Yes, both poles exhibit the same surface gauss strength.

8. Can a Magnet Have Only One Pole?

No, producing a magnet with just one pole is currently impossible.

9. How is Magnet Strength Measured?

Gaussmeters gauge magnetic field density on the surface, measured in Gauss or Tesla. Pull Force Testers measure holding force on a steel plate.

10. What is Pull Force and How is it Measured?

Pull force is the force needed to separate a magnet from a flat steel plate, using a perpendicular force.

11. Does a 50 lbs. Pull Force Hold a 50 lbs. Object?

Yes, the magnet's pull force represents its maximum holding capacity. Shear force is around 18 lbs.

12. Can Magnets Be Strengthened?

Magnetic field distribution can be adjusted to focus magnetism in specific areas, enhancing magnetic performance.

13. Do Stacked Magnets Strengthen?

Stacking magnets improves surface gauss up to a certain diameter-to-thickness ratio, beyond which surface gauss won't increase.

14. Do Neodymium Magnets Lose Strength Over Time?

No, Neodymium magnets retain their strength throughout their lifetime.

15. How Can I Separate Stuck Magnets?

Slide one magnet across another to separate them, using a table's edge as leverage.

16. What Materials Are Magnets Attracted To?

Magnets attract ferrous metals like iron and steel.

17. What Materials Are Magnets Not Attracted To?

Stainless steel, brass, copper, aluminum, silver are not attracted to magnets.

18. What AreWhat Are the Different Magnet Coatings? the Different Magnet Coatings?

Coatings include Nickel, NiCuNi, Epoxy, Gold, Zinc, Plastic, and combinations.

19. What's the Difference Between Coatings?

Coating differences include corrosion resistance and appearance, such as Zn, NiCuNi, and Epoxy.

20. Are Uncoated Magnets Available?

Yes, we offer unplated magnets.

21. Can Adhesives Be Used on Coated Magnets?

Yes, most coatings can be used with glue, with epoxy coatings being preferable.

22. Can Magnets Be Painted Over?

Effective painting is challenging, but plasti-dip can be applied.

23. Can Poles be Marked on Magnets?

Yes, poles can be marked with red or blue color.

24. Can Magnets Be Soldered or Welded?

No, heat will damage the magnets.

25. Can Magnets Be Machined, Cut, or Drilled?

No, magnets are prone to chipping or fracturing during machining.

26. Are Magnets Affected by Extreme Temperatures?

Yes, heat disrupts the alignment of atomic particles, affecting magnet strength.

27. What's the Working Temperature of Magnets?

Working temperatures vary by grade, from 80°C for N series to 220°C for AH.

28. What is Curie Temperature?

Curie temperature is when the magnet loses all ferromagnetic ability.

29. What is Maximum Operating Temperature?

Maximum operating temperature marks the point where magnets start losing their ferromagnetic properties.

30. What to Do if Magnets Crack or Chip?

Chips or cracks don't necessarily affect strength; throw away those with sharp edges.

31. How to Clean Metal Dust off Magnets?

Damp paper towels can be used to remove metal dust from magnets.

32. Can Magnets Harm Electronics?

Magnets pose a low risk to electronics due to limited field reach.

33. Are Neodymium Magnets Safe?

Neodymium magnets are safe for humans, but large ones can interfere with pacemakers.

34. Are Your Magnets RoHS Compliant?

Yes, RoHS documentation can be provided upon request.

35. Are Special Shipping Requirements Needed?

Air shipments require metal shielding for larger magnets.

 

36. Do You Ship Internationally?

We ship internationally through various carriers.

37. Do You Offer Door-to-Door Shipping?

Yes, door-to-door shipping is available.

38. Can Magnets Be Shipped by Air?
