Magnetic Field Strength

The Modern unit of field strength is the tesla (T), named after Nikola Tesla

(1856 - 1943 ), a serb who emigrated to New York to work in Thomas Edison's laboratory.

The tesla has largely replaced older units of magnetic field strength, the gauss and oersted, though the gauss is still in fairly common use. Particularly for static magnets used in healing.

Magnets used in healing typically have a field strengths in the range 200 - 2000 gauss.

1 tesla = 10,000 gauss.

Since the Tesla is a very large unit, therapeutic magnet strengths may be given in thousandths of teslas ( milliteslas, mT )

or even millionths ( microteslas, µT )

Example :-

2000 gauss   =  200 mT

200 gauss     =    20 mT
