does superconducting levitation fascinate you? even if you have no physics background, you are going to exactly understand how levitation works along with 7 other applications of superconductors so let's get started superconductivity  the first step to understand how things levitate is to understand what is a superconductor definition- it is a substance which offers no electrical resistance to any current flowing through it   the opposition to current in a material is a function of temperature, it increases and decreases with temperature but, there is a particular temperature below which the resistance becomes zero this temperature is the critical temperature(Tc) below the temperature Tc, the material becomes a superconductor conduction in metal takes place by electrons, but in superconductors, it is done by a pair of electrons these pairs of electrons are called cooper pairs a magnetic field induces currents in the superconductor these currents repel the external magnetic fie...
