Based on the image below the ferromagnetic material is best

Based on the image below, the ferromagnetic material is best described by which schematic

Solution

Ferro magnetic materials have property of becoming magnetized when those comes under the influence of the magnetic fields.

Those material attracts towards magnets and tries to get magnetized upon prolonged influence of magnetic field ferro-magnetic materials permanently becomes magnetic.

Here right side shows aligned magnetic field when ferromagnetic material comes under influence of magnetic field those try to align them self also. Here in 3rd case shows the same property of ferromagnetic materials.

Answer is C
