1. The problem statement, all variables and given/known data What direction does the force that the current carrying coil feel point to when a magnetic field is turned on? A magnetic field is turned on and points from bottom to top and passes through a current carrying coil that has current passing through it CCW. Here is a diagram https://stuff.mit.edu/afs/athena/course/8/8.02t/www/materials/PRS/Raw/PRS_W11D2.pdf (bottom of page 2) 2. Relevant equations F = ILBsintheta Lenz's law 3. The attempt at a solution From Lenz's law I know that once the magnetic field is turned on there is an increase in magnetic flux upwards. Which means there is an induced magnetic field downwards, which means there is a current passing through the wire that should be clockwise. But this question is weird because there is already current passing though the wire CCW, so I'm not sure exactly sure what happens to the current or the force when the magnetic field is turned on. I would really appreciate some help!
