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...
