- 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 prototype of an MRI consists of a set of 600 coils each having a radius of 0.20 m. To test its efficiency a 1.8 T magnetic field oriented perpendicular to the plane of the coils is shut off over a 3.2 second time interval. What is the induced current in the coils? The resistance is 15ohmsnillan Learning Activity on the Sun, such as solar flares and coronal mass ejections, hurls large numbers of charged particles into space. When the particles reach Earth, they can interfere with communications and the power grid by causing electromagnetic induction. For example, a current of millions of amps (known as the auroral electrojet) that runs approximately 100 km above Earth's surface can be perturbed. The change in the current causes a change in the magnetic field it produces at Earth's surface, which induces an emf along Earth's surface and in the power grid (which is grounded). Induced electric fields as high as 6.0 V/km have been measured. We can model the circuit at Earth's surface as a rectangular loop made up of the power lines completed by a path through the ground beneath. We can treat the magnetic field created by the electrojet as being uniform (but not constant) and parallel to Earth's surface near the surface. Consider a 1.0-km-long stretch of power line that is…
