The figure below shows a conducting rod sliding along a pair of conducting rails. The conducting rails have an angle of inclination of θ=30 degrees. There is a resistor at the top of the ramp that connects the two conducting rails R=2.3Ω. The mass of the rod is 0.42 kg. The rod starts from rest at the top of the ramp at time t=0. The rails have negligible resistance and friction, and are separated by a distance L=15.7 m. There is a constant, vertically directed magnetic field of magnitude B=1.5 T.
Find the emf induced in the rod as a function of its velocity down the rails. What is the emf when the velocity is 5.696E−03 m/s? .116 W
What is the rod's terminal speed? 0.01138 m/s
WHAT I NEED HELP WITH:
A) When the rod moves at its terminal speed, what is the power dissipated in the resistor?
For this I was using the equation P = V2/R and I got .00586 W which is wrong. What am I doing wrong?

- Experiments to study vision often need to track the movements of a subject’s eye. One way of doing so is to have the subject sit in a magnetic field while wearing special contact lenses that have a coil of very fine wire circling the edge. A current is induced in the coil each time the subject rotates his eye. Consider an experiment in which a 20-turn, 6.0-mm-diameter coil of wire circles the subject’s cornea while a 1.0 T magnetic field is directed as shown. The subject begins by looking straight ahead. What emf is induced in the coil if the subject shifts his gaze by 5.0° in 0.20 s?arrow_forwardA rectangular coil of wire has dimensions of 3 cm by 6 cm and is wound with 60 turns of wire. It is placed between the pole faces of a magnet that produces an approximately uniform magnetic field of 0.4 T. Suppose that the plane of the coil is turned from being perpendicular to the field to being parallel to the field in 0.25 seconds, what is the average voltage generated in the coil?arrow_forwardMagnetic forces can be used to accelerate projectiles to very high speeds in a so-called railgun. In the simplified version shown below, a voltage source drives current down two parallel ideal wires to a section of metal in contact with both wires. The metal has a resistance 0.6 mΩmΩ and weights 6 grams. We assume that the contacts between the wires and the section of metal are friction-less and that the metal can slide along the wires for a total distance of 1 m before exiting the railgun as a projectile. Our goal is to calculate what voltage that will cause the metal projectile to leave the railgun at the speed of sound (343 m/s), assuming it starts from rest. First, what constant force (in N) will accelerate the rod to the speed of sound in 1 m? Give your answer to 3 significant digits. Next, which voltage V will generate the necessary current to create this constant force? Give your answer to 3 significant digits.arrow_forward
