Question

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

Explanation:

Induced magnetism is easiest in soft ferromagnetic materials. Copper and aluminum are non-magnetic metals, air is a non-magnetic medium, while Permalloy is a nickel-iron soft ferromagnetic alloy with high magnetic permeability, making it highly susceptible to induced magnetism.

Answer:

C) Permalloy
