Explaining Static Magnets

One of the most frequent questions we are asked on the phone is the difference between our static magnets. What exactly is a  Neodymium magnet and why is it more expensive than our Ferrite magnets?

Well, put simply, Neodymium magnets are much stronger.

Ferrite magnets are those traditionally used in magnetic therapy. ferrite refers to their make-up- partially iron oxide and partially ceramic. This way of engineering magnets was developed in the 1950s, replacing centuries old carbon-steel magnets. Ferrite magnets were stronger, typically with a Tesla value of 0.5 to 1.

The 1970s brought another advance in magnets with the advent of Rare-Earth Magnets. Rare-Earth is a somewhat misleading name for a broad camp of magnets, of which Neodymium is the strongest. Rare-Earth magnets, nicknamed "neo"magnets are comprised of iron and boron, along with smaller quantities of so-called "rare" metals. Used for everything from hard-drives to jewellery clasps, their popularity as a strong and long-lasting magnet has only increased in recent years . Neodymium magnets tend to be around 1 tesla but some can even exceed 1.4 tesla (that's a massive 14, 000 gauss).
Here at magnetic therapy, our best-selling Gold Neodymium 9000 spot magnets are plated with gold to protect the magnet. They remain best-selling as they have an active life of up to 15 years, and are some of the strongest therapy magnets on the market. Here is a link to them on our website:

Just to put 9000 gauss in perspective, this video shows the power of a Neodymium magnets with a magnetic power of 14, 800 gauss. Now that's a powerful magnet!
