This block magnet is so big and powerful, we have nick named it the MAMMOTH. We believe this is the largest permanent magnet available in New Zealand. Our 50x25x13 mm magnet is considered a large neo magnet, but this is 16 time larger!!! This is not for the faint hearted. Extreme caution will need to be taken when handling this neodymium magnet. Before we dispatch this magnet, we will email you to make sure you are aware of the risks handling this magnet.

The cost to ship this magnet is different from all our other magnets as it must be transported by road or rail. The freight cost is $29.90.

Neo magnets are also called Neodymium magnets, Rare Earth magnets, Nd-Fe-B magnets, Neodymium Iron Boron magnets or NIB magnets. They are a permanent magnet made from an alloy of neodymium, iron and boron. Neodymium magnets have grades from N35 to N52 and are the strongest and cost effective permanent magnets manufactured.

The energy product is specified in units of Gauss Oersted. One MGOe is 1,000,000 Gauss Oersted. A grade N45 would have a Maximum Energy Product of 45 MGOe. The higher the grade the stronger the magnet.

Before purchasing, please read our page that has the Important Stuff You Should Know About Neo Magnets. This will help you to make an informed decision.

If swallowed, neodymium magnets can be lethal if 2 magnets join up. Strong magnetic fields can disrupt medical devices such as pacemakers. These magnets can severely pinch skin or crush fingers. Avoid use around electrical and magnetic devices such as TVs, computers, tapes, credit cards etc.
