Q: Why do neodymium magnets break easily?

The Neodymium magnets that you use are not actually made from solid chunks of metal, but are rather made by compressing a large amount of powder into blocks through a process called sintering. This is the reason they are so brittle.

Q: What do I need to pay attention to in the use of neodymium magnets?

Neodymium magnets are not children's toys. Keep the neodymium magnet at least 25 centimeters away from electronic devices. Keep the neodymium magnet at a very safe and long distance from people with pacemakers or implantable cardiac defibrillators.

Q: What grades of neodymium magnets are usually available?

In general, neodymium magnets are available in grades ranging from N35 to N55. The higher the grade or N number, the stronger the magnetism.

Q: How to separate two magnets correctly?

The Edge Technique Utilize the edge of table or desk by positioning the magnets where they are joined and then carefully pushing the magnets apart. Be sure to quickly separate the magnets and store far enough away from each other.

Very Strong and Delicate

These magnets are very strong and do a great job at holding however be careful letting them attach to one another too quickly as this often breaks magnets, I have already lost 5 of 20 ordered. There are other versions of this magnet with backing or protection that may better suit your need.

Too strong for amateurs use

These magnets were intended for middle school science lessons but were way too strong. Adults could barely pull them apart from one another so these would not work for 7th and 8th graders.
