Question

magnetic flux density for the current distribution in the free space

Answer 1

Answer:

The magnetic field vector B is defined by the force it would apply to a charge moving in it. B = F/qv, so the units are (N *s) / (C *m), which we call a Tesla, or T. This is also called flux density. Flux is then given by B*A, so it is in T*m^2, which we also call a Weber.
