A flux quantum (fluxoid) is approximately equal to 2×10^-7 gauss−cm2.A type II superconductor is placed in a small magnetic field, which is then slowly increased till the field starts penetrating the superconductor. The strength of the field at this point is 2/π×10^5 gauss
The penetration depth of this superconductor is
100 Å
200 Å
1000 Å
314 Å
