- 3. A2.6 mm radius cylindrical conductor has a concentric 1.2 mm radius hole in it. The conductor carries a current of 1.8 A. Assuming that the current is uniformly distributed across the cross-sectional area of this conductor, use Ampere's Law to find the magnitude of the magnetic field at a radius of 1.75 mm from the center of the conductor.Solar cells generate a potential difference when exposed to sunlight. In an experiment, you wish to charge a rechargeable battery by connecting it in series to an array of solar cells. You perform the experiment outdoors, in direct sunlight, when the intensity of solar radiation is 1000 W/m2. However, your solar cells only have an efficiency of 11% (that is, only 11% of the sunlight power transmitted to the solar cells is delivered to the rechargeable battery). While the circuit is connected, you measure at one instant the potential difference across the battery to be 4.90 V and the current in the circuit to be 0.25 A. What is the area of the array of solar cells? _____________ m2Patients undergoing an MRI occasionally report seeing flashes of light. Some practitioners assume that this results from electric stimulation of the eye by the emf induced by the rapidly changing fields of an MRI solenoid. We can do a quick calculation to see if this is a reasonable assumption. The human eyeball has a diameter of approximately 25 mm. Rapid changes in current in an MRI solenoid can produce rapid changes in field, with AB/At as large as 60 T/s.
