A) When a bar magnet is cut into half, each half will have only one pole
B) A magnet can be obtained from the iron in which all the electrons are spinning in the same direction
C) Iron, Nickel, and Cobalt are the three elements of a magnet
D) The earth acts as a huge magnet
The correct option is A) When a bar magnet is cut into half, each half will have only one pole.
The ends of the magnet are known as poles of a magnet. When a bar magnet is cut into half there are two smaller dipole magnets are formed. Magnets are made of small pockets that are known as domains. The magnetic moment of these domains are aligned in one direction. By cutting the magnet into half, the alignment of the magnetic moments remains unchanged.
