1)Some random problems... a) An electron (q = -1.6-10-19C) travels to the right on the page here at a speed of 105m while a constant magnetic field of strength 1.7T points out of the page toward you. What is the magnitude and direction of the magnetic force on the electron? b) A circular coil of radius 10 cm with ten turns initially sits with a magnetic field of 0.1 T along its axis. What is the magnetic flux through the coil? c) The coil in the previous part is now spun on an axis perpendicular to the field in a motion described by =sin(wt) where w=3 Hz. What is the EMF (voltage) induced in the coil as a function of time? d) Write the speed of light in a vacuum to eleven significant figures. e) In the figure below, all separate inductors have the same value, 6 mH. What is the effective inductance of the whole arrangement from the left end to the right? (The vertical straight lines are plain wire.) f) The intensity of sunlight at the earth's surface is approximately 1kW on a bright SoCal day. What energy density of electric field does this imply?
