Based on eq. (7), if the force between two current-carrying wires increases by a factor of four and the separation distance between the wires remains unchanged, by how much must the current in the wires have increased
F=ILB=IL?oI =?oLI2, (7) 2?r 2?r
so if r stayed the same
I^2 wnet up by a factor of 4
that means I went up by a factor of 2

Force between current-carrying wires: (a) Derive an expression for the magnitude of the force between two current-carrying wires of length l that are separated by a fixed distance D. (b) If the currents are parallel to each other, is the force between the wires attractive or repulsive? Use the various right-hand rules to justify your answer.
Discuss your understanding of the force between two current-carrying wires, change the direction of the current, and the distance between the wires. Sketch the graphs necessary for your explanation.
