An upright rectangular loop of height a and width b has a lightbulb attached to it, with some resistance R. It is immersed in a constant magnetic field with magnitude B0, pointing into the page. Now you want to turn on the lightbulb by using Faraday’s law of electromagnetic induction. Since the magnetic field is fixed and the dimensions of the loop are also fixed, the only way to change the magnetic flux in the loop is to rotate it, let’s say at some angular speed ω. Write down the value of the magnetic flux as a function of time.
The force on a wire is a maximum of 4.38 N when placed between the pole faces of a magnet. The current flows horizontally to the right and the magnetic field is vertical. The wire is observed to "jump" toward the observer when the current is turned on. If the pole faces have a diameter of 12.9 cm, estimate the current in the wire if the field is 0.184 T. If the wire is tipped so that it now makes an angle of 15.1° with the horizontal, what force will it now feel?
