- The 5-cm by 8-cm rectangular coil of a bicycle generator is rotating at a rate of 125 rpm in a 255-mT magnetic field. The output voltage of the generator is used to power a bicycle headlight that has a total resistance of 360 N. (a) How many turns are there in the coil if the peak output voltage is 1.8 V? N = turns (b) What is the rms-average current through the headlight? Irms mAA 0.230 m radius, 480 turn coil is rotated one-fourth of a revolution in 4.17 ms, originally having its plane perpendicular to a uniform magnetic field. (This is 60 rev/s.) Find the magnetic field strength needed to induce an average emf of 10,000 V. X TIn modern Magnetic Resonance Imaging (MRI), the system is resistance free. The resistance-free Magnetic Resonance Imaging (MRI) is created by submerging the solenoid electromagnet into a cryogenic liquid such as liquid helium (He).eHH The temperature of liquid helium (He) is 4 Kelvin (K), which is -4,520 Fahrenheit (F). What type of magnet creates the resistance-free system?
- Suppose you have a long, skinny conductor that is oriented with its long axis parallel to a uniform magnetic field. Suppose also that the conductor is moving along its long axis in a straight line at constant velocity v. Despite the motion of the conductor, no motional emf is induced. Why? The magnetic field is too uniform The velocity has no component normal to the magnetic field The velocity is too low The conductor is so long and so thin that its electrical resistance is too high005 A uniform electric field of magnitude 5.06 x 10 V/m throughout a cylindrical volume re- sults in a total energy of 2.95 µJ. What magnetic field over this same region stores the same total energy? Answer in units of T.suppose a conducting rod with length of 25cm is pulled along the a rotated U-shaped conductor (assume that resistance is negligible), the magentic field has a constant value of 37.2 mT and the constant velocity at which the rod is pulled is 5.5m/s. identify the minimum rate of energy input to the system to keep the rod moving at constant velocity if it has a resistance of 7ohms
