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!

Migraines and Magnets

There is a bit of a stir in the study of magnetic therapy of late, with Migraine treatments receiving particular attention.
Transcranial Mental Stimulation is a non invasive method whereby the neurons of the brain can be stimulated, monitored or treated through electromagnetic induction- that is, the application of a strong, pulsatîng magnetic device.
The theory was developed in the 80s in Sheffield, where it was noted that applying electromagnets to patients could help alleviate the symptoms of aura migraines, depresion, strokes and even hallucinations.
Initially, rTMS machines were restricted to testing facilities and specialised clinics. Machines were bulky, expensive and clinical results questioned:

In recent years, ENeura amongst others have developed a handheld version which has been getting very positive results from patients.Targetting aura migraines in particular the rTMS machine offers the chance at drug-free migraine treatment.
Here is a look at the machine:

Applied as and when the patient feels a migraine threatening, the machine promises to be extremely popular. As this machine indicates, exciting avenues of treatment are constantly being discovered in relation to magnets. Whilst oly avalable in north america and the australasia,the positive feedback from the product would indicate that TMS won't take much longer to get here...
