(H, H field, magnetic field, magnetizing field, magnetic field intensity)
(a field associated with magnetism)
The magnetic field strength (magnetic field, H)
is a vector field (H field) describing magnetic forces.
A different but related field is the magnetic flux density (B):
H describes the magnetic field generated specifically by electric
current flow (i.e., changes in the electric field) whereas B
additionally includes the magnetic effects of material within
the field that is magnetized or responds magnetically.
