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

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.

Answer

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

Answer

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