Problem 7:You are working on a design for an electromagnetic compass. A single circular loop of wire with an area ofA=1.3mm²is fixed to the face of the compass, and initially lies in a horizontal plane. While active, your circuit is designed to have a counter-clockwise direct current ofI=4.5A running through the loop, as seen from above. The compass is in a gimbal which allows the loop to rotate along any axis. You are field testing your compass in an area where the earth's magnetic field has a strength ofB=49T. Randomized VariablesA=1.3mm² I=4.5A B=49T =36
