Why we Cannot isolate north pole or south pole of a magnet?
Answer: Magnetic poles do not exist separately like positive and negative charges. This means that it is not possible to isolate a north pole of a magnet from its south pole by cutting the magnet from the middle. Whenever a bar magnet is cut into two halves, we get two new magnets, each with its north and south poles.
Why are there no isolated magnetic poles?
Instead, the two magnetic poles arise simultaneously from the aggregate effect of all the currents and intrinsic moments throughout the magnet. Because of this, the two poles of a magnetic dipole must always have equal and opposite strength, and the two poles cannot be separated from each other.
Why is the north pole magnetic?
The data showed that the position of the north magnetic pole is determined largely by a balance, or tug-of-war, between two large lobes of negative flux at the boundary between Earth’s core and mantle under Canada.
Why do magnets have opposite poles?
The magnetic field is the area around a magnet that has magnetic force. All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other.
Can magnet be created artificially?
Artificial magnets can be created by doping iron, nickel, and/or cobalt with other elements. Doping with rare earth materials has been particularly successful, producing very strong magnets.
Does magnetic monopole exit?
Answer : Magnetic monopoles do not exist because the magnetic field lines forms closed loops i.e. the field lines must start from one pole and terminate at the other. But if a monopole exits then the magnetic field lines will not terminate which is impossible. Hence, the magnetic field lines do not exist.
Can a magnetic monopole exist?
As implied by its name, the magnetic monopole consists of a single pole, as opposed to the dipole, which is comprised of two magnetic poles. As yet there is no evidence for the existence of magnetic monopoles, but they are interesting theoretically.
