The Law of Biot-Savart shows that the magnetic field of an infinitesimal current element decreases as 1/r^2. Is there anyway you could put together a complete circuit (any closed path of current-carrying wire) whose field exhibits this same 1/r^2 decrease in magnetic field strength? Explain your reasoning.

True or False The magnetic field at a radial distance R from a current element i dl is a maximum when the current element direction is at right angles to the radial line. Induced electric field lines are continuous, i.e. having no beginning or ending points. An arbitary shaped Amperian loop through which no currents pass may itself pass through a magnetic field.
