Hi Simon and thank you for your reply! I gave your hint a shot, and this is what I came up with: Since the coil is of N turns, the induced emf in the coil running current through it should be given by ε = -N(dø/dt). ε is also given by Ohm's law, ε = IR, meaning IR = -N(dø/dt) ⇔ dB/dt =...

Homework Statement Two solenoids are placed in a cartesian xy-coordinate manner with their bottoms pointing in the negative y-direction, and their tops pointing in the positive y-direction. The solenoids are placed a distance x from each other (on the x-axis). The solenoids are identical...
