A wire loop of radius 0.30 mlies so that an external magnetic fieldofmagnitude 0.40 T isperpendicular to the loop. The field reversesits direction, andits magnitude changes to 0.20 T in 2.0 s. Findthe magnitude of the averageinduced emf in the loop during thistime. Your response differs from the correct answerby orders ofmagnitude. mV
