How To Store My Neodymium Magnet ?

Neodymium Magnets and its strength

Neodymium magnets is made up of an alloy of neodymium, iron and boron. The neodymium are one of the most powerful magnets commercially available to buy. The strength of the neodymium magnets are defined by their grade. The grade range from N35 – N54, where

  • N stands for – Neodymium
  • numbers 35 to 54 stands for – Mega Gauss Oersteds (MGOe), measurement of strength of the magnet

If you are a magnet fisher you probably already own a Neodymium magnet and you are here to find out what is a safe way to store your neodymium magnet.

It is very important you take good care of your magnet so it can maintain its strength for long periods of time. You can store your neodymium magnet in special cases that are made for the magnet, or use an hard cooler box to store all of you magnet fishing kit.

Why Should I Protect My Neodymium Magnet & Store It Safely ?

Storing your magnet safely is vital to maintain the magnetic strength and also for safety reasons.

How Can my neodymium magnet lose its power ?

Neodymium magnets can break

Neodymium magnetic material are brittle and if dropped on hard surfaces can break into pieces. The magnetic strength depends on the size of the magnet so if your magnet breaks this will affect the strength of the magnet.

So you ask Anthony “If neodymium magnets are brittle, I am literally throwing my magnet around while magnet fishing why does my magnet not break?”

Great question, almost all of the neodymium magnet you buy for magnet fishing from the store are enclosed in a steel shell to protect the magnet.

Dangers of Neodymium Magnet

Neodymium magnets are extremely powerful. The larger the size the more powerful they are. They have some serious pull strength. When you keep one of these magnets near another magnet or other objects attracted by the magnet they can jump or pull with force and speed. You do not want to have your fingers in-between those objects. Your fingers will get severely pinched or squashed leading to serious injury or a lot of pain.
