Two parallel wires both carry currents directed from left to right .A circular wire loop lies in the plane of the two wires,
mid-way between them.As always, assume the currents are positive
charges. Sketch the changes in magnetic fields induced and the resultant
current direction in the loop when:
a. I1 is increasing and I2 is constant.
b. I1 is decreasing at a certain rate, and I2 is decreasing at twice that rate.
I know how to solve this with 1 wire and a circular loop...but I am confused with 2 parallel wires.. If I2 is constant in a) then the there is no emf and if I1 is increasing then emf will be clockwise... is that it? Thank you for helping..
