1. The problem statement, all variables and given/known data Along horizontal wire carries a current at 48 A. A second wire,made of 2.5 mm diameter copper wire and parallel to the first,is kept in suspension magnetically 15 cm below.Determine the magnitude and direction of the current in the lower wire.Is the lower wire in stable equilibrium? 2. Relevant equations F/l= u.I1I2/2(3.14)d u. -permeability of free space 3. The attempt at a solution The second wire is not falling down so the current in both wires must be the same direction.I dont't have any idea how to get the force ,because there is no lenght and mass.
