magnetic force/pull question

[a10ken]

Hi folks, I have just been asked the question: what is the power/strength of a magnet measured in, i.e. mm/cm/km for length, ml/cc for volume, etc,etc

can anyone on the physics side help

thanks

from many wiki's....

Magnetic field strength is one of two ways that the intensity of a magnetic field can be expressed. Technically, a distinction is made between magnetic field strength H, measured in amperes per meter (A/m), and magnetic flux density B, measured in Newton-meters per ampere (Nm/A), also called teslas (T).

just what I needed, thanks juju
