WebIn classical electromagnetism, magnetization is the vector field that expresses the density of permanent or induced magnetic dipole moments in a magnetic material. Movement within this field is described by direction and is either Axial or Diametric. The origin of the magnetic moments responsible for magnetization can be either microscopic electric … Web20 jan. 2024 · The average velocity (drift velocity) of electrons is reduced. Therefore, the magnetic field is also decreased. In short, The temperature decreases the speed of particles (and so the current), decreasing the strength of the magnetic field. You're assuming a constant voltage source produces the current.
