Myth 4: Not all magnetic therapy suppliers are telling you the truth about the strength of their magnets. Here’s a little known trick that they use to mislead you about the power of their products.

O.K. This explanation is going to get a little bit technical but nothing that you won’t be able to understand. Please do persevere and read it because it exposes a huge ‘trick’ that magnetic suppliers use to make you think that their products are more powerful than they actually are. Here’s how they do it.

Firstly; you have to understand two very straight forward things:

1. A magnet has 2 measurements of power (gauss), called the core or manufacturer’s gauss rating and the surface gauss rating.

2. The core, also known as manufacturing, gauss has no relation what so ever to the gauss rating (strength) that the magnet has when it is touching your skin.

In short, the core/manufacturer’s gauss rating is the measurement of strength at the very core (centre) of the magnet. This measurement is used in industry to denote a magnets ability to adhere to another magnet or a piece of metal. The core gauss is a much higher number than the surface gauss.

The core gauss has absolutely nothing to do with the strength (gauss) that is present when the magnet touches the skin. As soon as the magnetic field (known as flux) leaves the centre of the magnet it begins to spread across the surface of the magnet and out from the sides of the magnet. The ‘spreading’ of the magnetic field (flux) reduces the strength and weakens the power of the core gauss. The strength of gauss on the surface of the magnet is very logically called the surface gauss

The surface gauss is the strength that is vitally important in healing magnets. It is the only measurement that you need to be concerned with. Surface gauss is a much smaller figure than core gauss and it accurately represents the power of the magnet at the point of contact with your body.

How to identify if your magnets are as strong as they claim to be

Now, some magnetic therapy suppliers will quote the strength of their magnetic products in the core gauss rating and not the surface gauss rating, this misleads the customer into thinking they are buying a very high strength and superior type of magnet when in fact they are buying a relatively low strength magnet.

If you know what to look for, it’s easy to see if a magnetic strength quoted is core gauss or surface gauss, here’s how:

1. Core gauss are very high values usually between 10,000-15,000 gauss. A therapeutic magnet would never have a surface gauss of over 4,000.

2. Surface gauss is measured in hundreds or the low thousands, usually 500-4,000 gauss. Surface gauss is always measured to the nearest hundred, such as 800 or 1,700 or 2,500.

3. Core gauss are stated in exact numbers such as 11,290 or 12,480, or 14,570.

The table below shows the most popular magnetic strengths used in magnetic therapy, the approximate core and surface gauss for each strength on the skin is shown.

Magnetic strength on the skin Core gauss rating Surface gauss rating
500 gauss 3,950 500
800 gauss 10,000 - 11,000  800
1,000 gauss
1,200 gauss
1,500 gauss

12,000 - 13,000
2,000 gauss 13,000 - 13,500  2,000
2,500 gauss 13,500-13,800 2,500
3,000 gauss 13,800 - 14,500 3,000

One exception to the rule

There is one instance where a core gauss is stated and you may accidentally mistake it for a surface gauss. This is when you see 3,950 quoted as the gauss rating. This value is in fact a core gauss, it seems low enough to be a surface gauss but it is the core strength of a 500 gauss magnet.

Probably the highest percentages of people who are taken in by a supplier quoting core gauss and not surface gauss are duped by the 3,950 core gauss strength. This is because it sounds plausible. If you have surfed several websites and seen that 3,000 gauss is a common super strength magnet you wouldn’t be too surprised to see 3,950. You would in all likelihood assume that it was surface gauss and think that you have got the strongest magnet available.

In truth, what you will actually get is a fridge magnet with a surface gauss of around 500. It does not have sufficient strength to penetrate the skin, you will not receive any benefits and you’ll end up throwing it away and saying magnetic therapy is load of rubbish and a waste of money.

In this instance you will have wasted our money so please do not get taken in by this blatantly dishonest practice. To illustrate my point I have included here some direct quotes from 2 website that are ranked high in Google search engine:

These new pads have up to 2,519 of the high strength 3950 gauss disc magnets and have the highest mass of any Magnetic Mattress Pad available in the world. Besides having the highest count of super high quality magnets these high quality discs are also 33% thicker than our competitors

Hi-quality, powerful 3950-gauss ceramic magnets for deepest penetration - compare this to the standard 800 to1000 gauss ratings of our "competitors".

Please do not get taken in by this outright, intentionally deceitful tactic.
