Concept:Cutting a magnet does not destroy its magnetism; it creates two separate, complete magnets.
Explanation:Each piece of a split bar magnet automatically forms its own north and south poles.
This happens because the magnetic domains inside each piece realign to produce a full magnet.
The two pieces are called two new independent magnets.
Option A is correct.
Option B is wrong because a smaller magnet generally produces a weaker external magnetic field.
Option C is wrong because cutting a magnet does not create an electric field or electric charges.
Option D is wrong because the bar magnet is not demagnetized by cutting it into pieces.
Answer:Two new magnets are created. Therefore, the correct option is A.
