1. Sannino and Mloane are discussing magnets. Point out a flaw in their reasoning (a place where they can grow) and a strength in their reasoning (a glow). Explain why the grow needs work and why the glow Is correct. San nine: \"The electric force is distinct from the magnetic force because of the experiment where a charged balloon attracted both sides of a magnet. This isn't how magnets behave, so charges are not magnetic.\" Mloane: \"Yes, but magnetic fields are created by moving electric charges. therefore electric charges can create both electric fields and magnetic elds. We should really call it a single electromagnetic eld." San nino: \"No. We can't have a single field because that would mean we can add the electric and magnetic fields together. " Mloane: \"Yes! That would work, you've got it. We've unied electricity and magnetism.\" Johannino: \"You can'tjust add anything together!\" 2. A set of current carrying wires are as shown. A proton is launched directly between the _. __ __ _. _I i. l A wires. Calculate the force on the proton, " ignore gravity. ' -> (3)- - 'U' = 5mm W3 5. As shown in the diagram. there is a rod moving across conducting rails at a speed of 2 m/s. The apparatus is sitting in a 5T magnetic field. The Iightbulb has a resistance of 500. a. Which direction does the induced flux flow? Explain. ID. Find the EMF around the loop. c. What is the current through the Iightbulb? d. Can we use a setup like this to generate infinite energy by putting it on a hill? Explain why or why not. 6. At a certain location in the normem hemisphere. the Earth's magnetic eld has a magnitude of 42 FT and points down ward at 57 to the vertical. Calculate lhe ux ltu'ough a hori- zontal surface of res 2.5 m3
