Question
Please explain Three students are discussing a rectangular wire loop moving at a constant speed as it enters a region in which there is a uniform magnetic field perpendicular to the plane of the loop. The sides of the rectangular wire loop arc perpendicular or parallel to the leading edge of the magnetic field. Allison: "The current will increase as more of the loop gets into the field since there will be more magnetic flux inside the loop." Blanca: "I think the current in the wire loop will start out big and then decrease as the loop moves into the field region since less of the loop will be outside of the field." Chithra: "No, the current in the wire loop will be constant from the time the loop starts into the field region until it is fully into the field region. Then the current will go to zero." With which of these students do you agree? Allison_____Blanca_____Chithra_____None of these students_____ Explain your reasoning.Explanation / Answer
Allison: The induced current is directly proportional to induced voltage or change in flux.
as B is constant, teh flux will incraese as more area gets into the magnetic field
