This has been bothering me for a while. Consider a varying magnetic flux through a closed loop. Faraday’s law says the integral of E around the loop is V. This seems to be OK if the loop itself is split and joined with some resistance and with a voltmeter we measure across the resistor. However, if the loop is now closed we are measuring across effectively a short circuit and the voltage must be zero or very low but in any case not the emf developed by the varying magnetic flux. It also seems to work if we measure halfway around the loop and then double the measurement but again doesn’t work going 359.99 degrees aroung the loop. Is there something I am missing here? Probably.
