Definition:
The International System unit of field intensity for magnetic fields is Tesla
(T). One tesla (1 T) is defined as the field intensity generating one newton (N)
of force per ampere (A) of current per meter of conductor:
T = N × A-1 × m-1 = kg × s-2 × A-1
Certain other non-SI units, like Gauss (G), are still occasionally used.
A magnetic field of one tesla is quite strong. That is why magnetic fields are
usually expressed in microtesla (µT). Typical values of field intensity for some
magnetic fields are: S
