1) An electric generator rotates a conducting coil with 58 turns through a magnetic field of 6.13x10^-3 T with an angular frequency of 5.0x10^5 Hz. If the coil has an area of 6.95m^2, what is the RMS voltage generated by the generator?
2) Suppose you are building a solenoid for an apparatus. The experiment requires a uniform magnetic field of 4.24x10^2 T. If the cross-section needs to be circular with an area of 0.28m^2 and 2.32m tall, what is the shortest length of wire that you will need to use if your power supply can give up to 2.78x10^3 A of current?
3) The picture below shows a simple electric motor with a square loop of wire with an area of 0.56m^2 and 151 turns. If the current in the loop (2.94 A) flow clockwise in a uniform magnetic field of 2.75 T, what is the peak torque on the loop and what direction will the loop spin?
South [ ] North ****note** the angle of the box in middle is represented by ''
4) If the motor described in the previous question undergoes 32 revolutions, how high could it lift a 853.5 kg car?
