12. * Jacob has been studying the effects of magnetic fields on straight conductors and has hada strange idea. He wants to make himself levitate using this principle. He thinks that by using asteel bar 2m long (and a mass of 10kg) he could pass enough current through it that if he hungon to it, as long as he was electrically isolated, the Earth's magnetic field (around40μΤ.) wouldlift up the bar and him along with it.a. Under what conditions, if at all, might this be possible?b. Aside from the risk of electrocution, what do you believe the largest problem with thissituation would be? Use calculations to help substantiate your response.

Let us analyse the question in step 2.

3. DETAILS MY NOTES You are working during the summer at a company that builds theme parks. The company is designing an electromagnetic propulsion system for a new roller coaster. A model of a substructure of the device appears in the figure below. The rod is of length d = 1.00 m and mass m = 0.700 kg. The rod carries a current I = 100 A in the direction shown and rolls along the rails of length L = 15.0 m without slipping. The entire system of rod and rails is immersed in a uniform downward-directed magnetic field with magnitude 8 = 1.90 T. The electromagnetic force on the rod is parallel to the rails, causing the rod to roll to the right in the figure. When a full-scale device is produced, this rod will represent the axle of wheels on which the car and i on the grounds of the company. By projecting the rod from the rails in a horizontal direction from a height h = 1.80 m, the projection speed can be determined from how far from the ends of the rails the rod hits the ground. Your…

13. You have the apparatus shown in Figure P21.13. A circular metal plate swings past the north pole of a permanent magnet. The metal consists of a series of rings of in- creasing radius. Indicate the direction of the current in one ring (a) as the metal swings down from the left into the magnet- ic field and (b) as the metal swings up to- ward the right out of the magnetic field. Use Lenz's law to justify your answers. Figure P21.13 Metal plate Magnet N
