Question

Which of the following statements are true about ferromagnetic materials? ( Select all that may apply )

Answer

Applying an external magnetic field to a ferromagnetic material will cause all the domain walls that are more or less aligned with the field to become the same size, as a result of them all being exposed to the same level of flux density.

Answer

Domain wall motion is the reorientation of the magnetic domains when a ferromagnetic material is removed from an externally applied magnetic field.

Answer

Applying an external magnetic field to a ferromagnetic material can cause it to become a permanent magnet.

Answer

A coil wrapped around a ferromagnetic core will experience the same flux density as a coil wrapped around a torus filled with air, only if the current passing through the coils are the same.

Answer

Ferromagnetic materials have magnetic domains consisting of magnetic moments in one direction.
