(d) Determine the rate at which energy is dissipated in the circuit when the bar has reached its constant final speed.
Homework Answers
at constant final speed ,
Current = I = mgsinθ/Bl ( see part - b for reason)
Now,
Rate of Energy dissipation = I2R = [ mgsinθ/Bl ]2R

A conducting bar of mass m is placed on two long conducting rails
A conducting bar of mass m is placed on two long conducting rails a distance l apart. The rails are inclined at an angle theta with respect to the horizontal, andthe bar is able to slide on the rails with negligible friction. The bar and rails are in a uniform and constant magnetic field of magnitude B orientedperpendicular to the incline. A resistor of resistance R connects the upper ends of the rails and completes the circuit as shown. The...

Two parallel conducting rails a distance l apart are connected
at one end by a resistance R in series with battery of emf E. A
conducting bar completes the circuit, joining the two rails
electrically but free to slide along them. The whole circuit is
perpendicular to a uniform magnetic field B, as shown in (Figure
1). The bar is initially at rest, and nothing is pulling it.

The figure below shows a bar of mass m = 0.280 kg that can slide without friction on a pair of rails separated by a distance ℓ = 1.20 m and located on an inclined plane that makes an angle θ = 29.5° with respect to the ground. The resistance of the resistor is R = 2.20 Ω, and a uniform magnetic field of magnitude B = 0.500 T is directed downward, perpendicular to the ground, over the entire region...
