Q: What are neodymium magnets?

A: Neo magnets are a member of the rare earth family and are currently the strongest permanent magnets in the world! They are composed of neodymium, iron, and boron (NdFe)

Q: What does the grade N35, N40, N42, N45, N48, N50 mean?

A: These magnets come in a variety of grades which are measured in units millions of Gauss Oersted. Basically, the higher the grade, the stronger the magnet and its pull force.

Q: What does pulling force mean?

A: Pulling force is a measure of magnetic strength. It is the amount of force required to remove a magnet parallel to a solid magnetic surface, such as a steel plate.

Q: How are these magnets polarized?

A: Through thickness.

Q: Do I have to worry about temperature with neodynium magnets?

A: Yes. They are sensitive to heat so do not heat them above 175°F (80°C) If you do, they will begin to lose their magnetic strength. This normally applies only to industrial usage of heating the magnets; normal application will not affect the strength of the magnets.

Q: Do you ship overseas?

A: Currently we are only shipping to USA addresses.

Q: How are you able to provide the same product for half the price of office supply stores?

A: Our primary focus is on business card magnets and we manufacturer them ourselves! As such, we are able to pass the savings on to you that other companies simply can’t do for the quality of magnets that we have.

Q: Why are neodymium magnets coated?

A: They are coated in nickel to prevent oxidation (rust). Our magnets are well coated in nickel to prevent rust.

Q: If I stack two neodymium magnets together, does their strength double?

A: Yes. For example, two magnets rated with a individual pulling force of 50 lbs will have a combined pulling force of 100 lbs when stacked together.

Q: Do I need to be wary of electronics around these magnets?

A: Yes. As a general rule of thumb, try to avoid close contact between magnets and electronic media. More common items to be damaged are televisions, computer monitors, and credit cards.

Q: Should I be aware of any health or safety issues with neodymium magnets?

A: As a precaution, magnets should not be near pacemakers and similar medical devices. Magnets are sometimes used to relieve pain from conditions such as arthritis, back pain, and carpal tunnel syndrome.


Magnets should be handled carefully to avoid personal injury and damage. It is very easy to pinch fingers between attracting poles. Please keep magnets away from children and pregnant women. These magnets are intended for industrial purposes only and should be handled with care by ADULTS only.

Q: Do neodymium magnets lose strength over time?

No. They do not naturally lose any appreciable strength and will last your lifetime! Make sure to not heat them above 175 degree F (80 degrees C).

Q: Is cheaper always better when it comes to magnets?

A: Not Necessarily. You are paying for a quality product at discounted prices from BuyStrongNeoMagnets.com
