## flux density and field strength ### Magnetic field, field strength, and flux density

In physics, there are two different attributes of a magnetic field: The "magnetic field strength". Usually given the symbol H. Measured in amps per metre (A/m). The "magnetic flux density". Usually given the symbol B. Measured in teslas (or microteslas or gauss). In electromagnetism theory, it is absolutely clear that these are different ...

The flux can be distributed widely, producing and extended and weak field, or it could be very concentrated, resulting in a strong compact field. There are two measurable parameters that are effected by the flux distribution, these are field strength and flux density. Field strength. A larger m.m.f. will naturally produce a stronger field.
