Repulsion only occurs when two like poles of a magnet exist while attraction can occur between unlike poles of a magnet and/or between a magnet and a magnetic material.
Repulsion is the only sure method since it test L’s the polarity of magnets, I.e like poles repels unlike poles attracts but attraction can between unlike poles or between poles of a magnet and a magnetic material
replusion occurs only between like poles of a magnet whereas attraction occurs between unlike poles and between a pole and a magnetic material
I concur with you.
Repulsion only occur between like poles while attraction occurs between unlike poles and between a pole and magnetic material
Repulsion only occurs between the like poles of the magnet while attraction can occur between two unlike poles of magnets or between a pole and a piece of an unmagnetized magnetic material.
