An electricity and magnetism problem by Viki Zeta

True or False?

Magnets are a unique bond. They still exists with their pairs, even when split into trillions of small parts. However, it is possible to manipulate certain substances so that their magnetic field is similar to the magnetic field exerted by a magnetic monopole.

first step was making a Bose-Einstein Condensate - a small cloud of atoms cooled to a few billionths of a degree above absolute zero. The cooling process involves shooting atoms in a cold gas with lasers, sapping the atoms of their momentum, and then carefully manipulating the atoms with magnetic fields to slow them down even further. At this temperature, the atoms are almost stationary, and weird quantum effects start to happen. The atoms begin acting very strange and form a new kind of matter - different from the solids, liquids, and gasses we are used to. The researchers then carefully applied finely tuned magnetic fields to the strange matter, forming tiny tornado-like vortexes in the fluid. monopole field animation.gif Aalto University This animation, taken from a YouTube video posted by the researchers at Aalto University, shows how the monopole is made. By carefully balancing out external magnetic fields to move a point at the base of a vortex into the middle of the condensate, the condensate itself begins to emit an outward pointing monopole-style magnetic field. The researchers call this the "hedgehog configuration."

This is the quote from the university, who tried to create a monopole magnet. Basically every electrons and portions exerts a magnetic fields that emit magnetic field or of them, known as monopolic behaviour. So coming down temperature physics of electrons and magnetism showed various monopolic results
