If the loop consists of straight sides – e.g., a rectangular loop – then the force applied to the loop is the sum of the forces applied to each side separately, as determined by Equation \ref{m0017_em...If the loop consists of straight sides – e.g., a rectangular loop – then the force applied to the loop is the sum of the forces applied to each side separately, as determined by Equation ???. However, we wish to consider loops of arbitrary shape. In terms of the theory developed in this section, a current I1=+1.2 A flows from the positive terminal of the battery to the load on one conductor, and a current I2=−1.2 A returns to the battery on the other conductor.
