Why magnetic mono-pole does not exist?

In physics, the idea of the magnetic monopole is a hypothetical situation. Just like how we have the positive and the negative charges in current, in the same way, there are dipoles - North pole and the south pole. These magnetic charges always exist in pairs - dipole and never as a monopole.

The main reason is that our universe is not symmetric. The electricity is directly related to the magnetic field. Electricity has a positive and negative charge that either attract or repel each other. In the same way, magnetism also has the north and the south pole. But both electricity and magnetism are entirely different:

 

• In electricity, you can have the positive and the negative charges configured together or can also exist individually like a proton or an electron.
• In magnetism as well, you can have the north and the south pole configured together, but not in isolation. 

Hence, magnetic monopoles do not exist.

 

 The laws of electromagnetic induction tell us that if you have an electric current flowing inside a wire, then it creates a magnetic field, perpendicular to the direction of flow of current. If the current-carrying wire is bent, then there is a magnetic field inside the loop. Since the laws of Physics are symmetrical, it goes both ways. Hence, we can have electric charges, electric currents and electric fields, but only magnetic fields and no magnetic current or charges. 

 

Therefore, there is a fundamental asymmetry between the electric and the magnetic properties. 

Blas Cabrera, a famous physicist, performed a series of experiments to prove the existence of the magnetic monopole and failed. Hence, the main reason for the non-existence of the magnetic monopole is the asymmetric nature of the universe.

Magnetic mono-pole does not exists, because magnetic field lines always forms a closd loop. If it arises from one pole, then it has to terminate on other one, to form close loops, which is opposite pole, hence due to this property magnets always found in dipole.. but by some special method,scientists created monopole in lab, but it is not permanent,,,for more information u can call me or mail me. read less
