Homework Statement


I am stuck on a HW problem. A square loop of copper wire falls out of a side 'a' and radius 'r' falls outside of a magnetic field 'B'. How does one find the terminal velocity?
B = 1.2T
a = 5cm
r = 1mm

Please help me set up this problem so I can solve it and figure out what is going on!

Thanks,
Ryan---

Hi Ryan! Welcome to PF! :smile:

Forget about acceleration!

Terminal velocity means that the acceleration is zero!

So just balance the magnetic force against gravity. :wink:
