Only ax because component z has been cancelled due to the existence of a pair of z-component in opposite direction.
Z-component has been cancelled.
HΦ is all the same along Amperian path. It implied that HΦ is constant in integration
*isolated means 2 different charge (or pole) can be splitted.
not conservative
ConservativeIt implies that B is constant.Therefore,
