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. Induced electric field lines have a beginning and end point. The negative sign in Faraday's Law (Lenz's...
