You take your trusty 120 turn solenoid, with 20 cm diameter and spin it at a rate of 10 times per second in a magnetic field that you have constructed with two gigantic neodymium magnets, creating a uniform magnetic field. You are spinning the solenoid so that its rotation axis is perpendicular to the magnetic field direction. a) What field strength do you need to create a peak emf voltage of 150 V? (Hint: use flux as a function of...
