Maxwell`s Equations
... Let the current on the central wire be in the +z direction. In the quasistatic approximation (current changes slowly), the magnetic field is circumferential. A changing magnetic field in this direction is analogous to the current for a solenoid, which produces a longitudinal (in z direction) magneti ...
