👉 In physics, a supercontribution is a phenomenon where the energy density of an object increases due to an external magnetic field. This effect is known as the "superconducting transition" and occurs in materials with a high value for the Fermi velocity (v_F), which is the speed at which electrons are accelerated by a magnetic field. For example, consider a material that has a superconductor density of 10^28 cm^-3. If we apply an external magnetic field
