Electromagnetism questions Answer all questions.Include all the steps. 1) A step up transformer has exactly 50 turns in it's primary coil and 7000 in it's secondary. If the applied emf in the primary is 120V, what emf is induced in the secondary coil? 2) A coil with 205 turns of wire, a total resistance of 23 ohm, and a cross sectional area of 0.25m2 is positioned with it's plane perpendicular to the field of a powerful electromagnet. What is the average current induced in the coil during the 0.25s that the magnetic field drops from 1.6 to 1T? 3) A 6m wire carries a current of 7A towards the x direction. A magnetic force of 7 x 10^-7 N acts on the wire in the y direction. Find the magnitude and direction of the magnetic field produced. 4) A proton moves perpendicularly to a magnetic field that has a magnitude of 4.2 x 10^-2T. What is the speed of the particle if the magnitude of the magnetic force is 2.4 x 10^-14N? 5) What is the shape of the magnetic field produced by the straight current carrying conductor
