Two parallel cylindrical wires made of lead have diameters D=4mm and the distance between their axes is L=5mm.
Both wires are in superconductive state. The wires carry currents I=30A each in opposite directions.
What is the force of magnetic relpulsion F between the wires per unit length (per 1 meter)?
Note:
Meissner effect: magnetic field does penetrate inside bulk lead (type I superconductor).
I asked this question 16 times in physics section, and got no answer. Maybe matematicians could help me.
