1. A square loop of wire is 15cm on each side. It lies in a plane that makes a 450 angle with a 0.8T magnetic field. a. What is the magnetic flux through this loop? b. The magnetic field is then increased to 1.5T in 2s. What current is induced in the wire if the resistance is 0.050? 2. I have a cell phone charger that converts household 120V electricity to 20V. If there are 150 turns in the primary coil, how many turns are in the secondary coil? If the output current is 1.5A, what is the input current
