poles of a magnet cannot be separate give reason

magnetism kullabs com

the poles of a magnet cannot be separated a magnet has more force at its ends than in the middle reason the molecular magnets are arranged in an open chain so that the north pole or the south pole of molecular magnets lie in the same direction which gives strong force at the poles whereas two opposite poles are

is copper magnetic? - terpconnect

if you have a strong enough magnetic field all matter is magnetic but copper is so weakly magnetic that we can't observe it without very very large magnetic fields so the short answer is no copper isn't magnetic this can quickly be tested by trying to pick up a penny with a magnet but copper will interact with magnets in
