5. A transformer is plugged into the wall in North America (Vms. 120 & f = 60Hz). There are 4,000 turns in the primary coil and 100 turns in the secondary coil. The secondary is then connected to a solenoid that is 20cm long, has a circular cross section with radius 2cm, and has 5,000 turns. The solenoid acts as both an inductor in the secondary circuit and for production of a magnetic field. Inside the solenoid, the magnetic field will change with time. What is the maximum strength of the magnetic field? Primary (Input) ooooo Secondary (Output)
