Conventional current flows in a ring in the direction indicated in the diagram (if you stand at location A , on the +x axis, and look toward the ring, current flows clockwise). At each of the locations labeled by a letter, use the right hand rule to find the direction of the magnetic field at that location, due to the current in the ring. Location A -x -x Location B +x +x Location C -x -x Location D +x +x Location E

The radius of the loop is 0.07 m. Calculate the magnitude of the magnetic field at a distance of 0.37 m from the loop, along the axis of the loop. B = 3.46e-8 3.46e-08 T (b) What would the magnitude of the magnetic field be at the same location if there were 100 loops of wire in a coil, instead of one loop? B
