Magnetism and electromagnetismQuestion 170 of 1506

A steel bar is exposed to flux until all of its atoms line up. What is true of the bar now?

It slowly loses all of its magnetism
It is saturated, so more flux adds nothing
It gets stronger with more flux
It changes into a non-magnetic metal

Show answer

Correct answer: It is saturated, so more flux adds nothing

Once every atom is lined up, the bar is saturated. More flux cannot add to its strength.
