Magnets Frequently Asked Questions
Neodymium or Ferrite, which one is the best?
This is a tough question, since the determining factor is the intended role of the magnet. Ferrite magnets, although weaker, are surely cheaper, while neodymium magnets are stronger and therefore more expensive.
How do you take magnets apart?
Is it ok to use a Plastoferrite magnet as a counterpart for a Neodymium one?
How do you make magnets adhere to non-magnetic surfaces?
How can magnets become unmagnetized?
What do the letters M, H, SH, UH and EH mean?
What N35, N38, N40, N42, N45, N48, N50, N52 all stand for?
Are the countersunk and adhesive tape magnets sold with both north and south polarity?
Yes they are. We always provide our customers with half and half polarities to guarantee that, no matter the final usage, the magnets can be made to stick together or against a metal surface without issues!
Do north and south polarities have the same adhesive force?
How are north and south polarities made?
Can neodymium magnets be cut?
Can you use magnets in humid environments or underwater?
Neodymium magnets rust easily, therefore it is very risky to use them in humid environments if not adequately protected.
The solution to this problem is to use plastic-encased magnets or resin-coated pot magnets.
What coatings are available?
Among our coatings you can choose between zinc, nickel, gold, and black epoxy.
If the magnet has to come in contact with the skin, you would want to opt for a zinc-coated one. This guarantees that the magnet is nickel-free. Otherwise, the differences between the two coatings are just minor and cosmetic, the nickel being shinier and smoother.
Gold and black epoxy coatings offer a different color than the standard gray, but do not improve the grade of protection.
What does “marked” mean?
A marked magnet has a red or black dot on the relevant pole. This way the client knows the correct polarity and it becomes easier to assemble the magnets together (north against south).
Why are there magnets placed in pots like those in the magnetic system category?
Can Neodymium magnets lose their magnetism?
What temperature is safe for neodymium magnets?
What is the force direction of our neodymium magnets?
What does axial magnetization mean?
What factors make neodymium magnets go up in price?
What are ferrite magnets made of?
What applications are most common for ferrite magnets?
How much do ferrite magnets cost?
It is a common misconception that ferrite magnets are cheaper than neodymium ones.
Having less adhesive force, in order to reach the same one as a neodymium magnet the ferrite magnet will have to be quite bigger, raising its cost.
