Ferromagnetism

Ferromagnetism is a mechanism by which some materials show magnetic properties. Iron and magnetite, an oxide of iron, are two naturally occurring materials that show the property of ferromagnetism. The word ferromagnetism is derived from the Latin name of iron, "Ferrum" as it was the first observed material to show such property. The property of ferromagnetism is shown by only a few substances such as iron, nickel, cobalt, and their alloys. Some transition metals and alloys of rare-earth metals also show ferromagnetism.

Question

A metal ring 4.70 cm in diameter is placed between the north

perpendicular to the magnetic field. These magnets produce
an initial uniform field of 1.12 T between them but are
gradually pulled apart, causing this field to remain uniform but
decrease steadily at 0.240 T/s.
