A horizontal rod of length L carrying a current I, is suspended at right angles into a horizontal magnetic field (as shown in the sketch of the previous problem). The strength of the field is B. The magnetic force on the rod is measured by the balance and is found to be F. (a) What is the current in the rod in terms of the above variables? (b) Calculate the current if the force on the rod is 0.15 N, its length is 0.20 m, and the magnetic field is 0.054 T. (c) If the magnetic force on the rod is downward, in what direction is the current running in the circuit? (Clockwise or counterclockwise?)

I need help with 25-10. Thank you! I will give a thumbs up.
Transcribed Image Text:25-10. A horizontal rod of length L carrying a current I. is suspended at right angles into a
horizontal magnetic field (as shown in the sketch of the previous problem). The
strength of the field is B. The magnetic force on the rod is measured by the balance
and is found to be F.
(a) What is the current in the rod in terms of the above variables?
(b) Calculate the current if the force on the rod is 0.15 N, its length is 0.20 m, and the
magnetic field is 0.054 T.
(c) If the magnetic force on the rod is downward, in what direction is the current
running in the circuit? (Clockwise or counterclockwise?)
