Webmagnetic field strength, also called magnetic intensity or magnetic field intensity, the part of the magnetic field in a material that arises from an external current and is not intrinsic to the material itself. It is expressed as the vector H and is measured in units of amperes per metre. The definition of H is H = B/μ − M, where B is the magnetic flux … WebApr 24, 2016 · For instance a small bar magnet has a field strength of around 0.01 tesla. The Earth’s magnetic field is much weaker than this. It varies between 30-65 millionths of a tesla – alternatively described as 30-65 microtesla – and is stronger near the magnetic poles and weaker near the equator.
