"MAGNETISM can either pull the two objects together or push them apart, depending on which way the magnets point. Most importantly, it depends on what is going on with the electrons in the material, since each electron is like a tiny magnet itself. Most materials feel very little magnetic force because their electrons act like magnets that are pointing every which way, more or less equal numbers pulling or pushing." https://lnkd.in/evABxQC View in LinkedIn

GRAVITY. "Gravity and magnetism are not the same thing. In fact, they are completely separate forces. Gravity is a force that acts between any two objects with mass. No matter what they are made of, both objects get pulled towards each other just because they have mass." https://lnkd.in/evABxQC View in LinkedIn

ZERO GRAVITY. "Let's think about what a superconductor really is: it's a material in which electrons are able to flow very easily. Electrons flow through superconductors with no resistance, so that when magnetic fields get close to a superconducting material, the superconductor forms small currents on its surface, cancelling out the incoming magnetic field." https://lnkd.in/emW6Tsg View in LinkedIn

HOW IT WORKS. "Inside each magnetic flux tube superconductivity is locally destroyed. The superconductor will try to keep the magnetic tubes pinned in weak areas (e.g. grain boundaries). Any spatial movement of the superconductor will cause the flux tubes to move. In order to prevent that the superconductor remains "trapped" in midair." https://lnkd.in/emW6Tsg View in LinkedIn

FLUX TUBES. "Superconductivity and magnetic field [sic] do not like each other. When possible, the superconductor will expel all the magnetic field from inside. This is the Meissner effect. In our case, since the superconductor is extremely thin, the magnetic field does penetrate. However, it does that in discrete quantities (this is quantum physics after all! ) called flux tubes." https://lnkd.in/emW6Tsg View in LinkedIn
