1. The problem statement, all variables and given/known data A packed bundle of 100 long, straight, insulated wires forms a cylinder of radius R=.5cm a. if each wire carries 2A, what are the magnitude and direction of the magnetic force per unit length acting on a wire located .2cm from the center of the bundle? 2. Relevant equations B = μoI / 2(pi)r ??? 3. The attempt at a solution I found B to be .008T. but now I don't know what to do.
