Suppose a current is flowing in an infintessimally small diameter wire. The magnetic field strength at a given point is proportional to the current flow
and inversely proportional to the perpendicular distance to the wire. But this means
as the point approaches the wire, the magnetic field strength goes to infinity.
Something is not right. Please explain.
