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
Homework Answers
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
