Properties of Mangets

[MadMango]

I have never worked with magnets, but read an interesting article in R&D Magazine. The National High Field Magnetic Labratory in Florida has developed a magnet with a field strength of 21.1 Tesla, with a stored energy of 40MJ.

I'm trying to relate this magnet to common "every day" magnets that I might be used to seeing, such as cabinet latches, inductive switches, etc. Could someone give a few examples of what a 21.1 Telsa magnet is capable of so I can get an idea of it's "scale"?

it is roughly x100 larger than the fields that you are used to dealing with.

you should look up their safety manual on their web site.

1 Tesla is 10000 Gauss and the small bar magnets which we use in physics practicals have a strength of 100 Gauss or 0.01 Tesla. Earth's magnetic field strength is 0.5 Gauss or 0.00005 Tesla.

Magical water treatment people fool us with 30000 Gauss or 3 Tesla magnets.
