Question

which of the following would experience induced magnetism most easily? a) air b) permalloy c) aluminum

Explanation:

Induced magnetism is easiest in ferromagnetic materials. Permalloy is a ferromagnetic alloy (high magnetic permeability), air is non - magnetic, and aluminum is paramagnetic (weaker magnetic response than ferromagnetic materials). So Permalloy experiences induced magnetism most easily.

Answer:

B) Permalloy
