A voltmeter is being used to measure a 60 [Hz] voltage across a resistor in a circuit that is inside of a lab room. The two leads going from the voltmeter to the resistor are 5 [cm] apart and 2 [m] long, forming a rectangular loop with the voltmeter on one side and the resistor on the other side. Inside the lab there is a 60 [Hz] magnetic field coming from some equipment in the room. The magnetic flux density vector coming from this equipment has a peak magnitude of B0 = 0.01 [T] and the direction of the magnetic field vector from the equipment is at an angle of 45 from the normal to the rectangular loop formed by the leads. Calculate the peak magnitude of the extra (error) AC voltage that the voltmeter will read that is in addition to what the voltmeter is supposed to be reading.
