SUMMARY

The discussion focuses on deriving the terminal velocity (Vt) of a conducting rectangular loop falling into a magnetic field. The established formula for terminal velocity is Vt = (MgR) / (B²w²), where M is the mass of the loop, R is its resistance, B is the magnetic field strength, and w is the width of the loop. The problem emphasizes the relationship between the forces acting on the loop and its motion through the magnetic field. Participants express confusion regarding the application of the relevant equations to arrive at this conclusion.

The Attempt at a Solution



HAve Nooooo Clue!
 
Physics news on Phys.org
it should be Vt = mgR/B2w2
 
Use the formula for the force on a current carrying wire in a uniform magnetic field where the wire is moving with respect to the magnetic field.
