Magnetic material that moves from stronger to weaker part of magnetic field is
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → copper
A diamagnetic substance is weakly repelled by a magnet, so in a non-uniform field it moves from the stronger to the weaker region. Paramagnetic and ferromagnetic substances are attracted and move the other way.
Option (3) copper — Correct. It is diamagnetic, so it moves towards the weaker field.
NCERT (2026-27):
Diamagnetism – “… Diamagnetic substances are those which have tendency to move from stronger to the weaker part of the external magnetic field. In other words, unlike the way a magnet attracts metals like iron, it would repel a diamagnetic substance.”
