The behavior of ferromagnetic domains in an applied magnetic field gives rise to:

Correct answer: A. Hysteresis

  • A. Hysteresis
  • B. Ferromagnetism
  • C. The Curie law
  • D. Gauss's law for magnetism

Explanation

Magnetic hysteresis occurs when an external magnetic field is applied to a ferromagnet such as iron and the atomic dipoles align themselves with it. When the magnetization of ferromagnetic materials lags behind the magnetic field this effect can be described as the hysteresis effect.

About Magnetic Flux Density

Magnetic flux density measures the magnetic force acting on a current carrying conductor or moving charge in a magnetic field. Work includes the relations B equals F divided by IL and F equals qvB, the tesla as its SI unit, field direction and the distinction between flux density and magnetic flux.
