Question

A rectangular wire loop is pulled at a constant speed into a region in which there is a uniform magnetic field into the page. Uniform external magnetic field Identify whether effects 1-7 listed below could result because the loop is moving at: (a) a constant velocity approaching the region of the magnetic field but has not yet entered it. (b) a constant velocity entering the region with 1/3 of the loop inside the region of the magnetic field. (c) a constant velocity with the entire loop within the region of the magnetic field. (d) a constant velocity leaving the region with 1/3 of the loop inside the region of the magnetic field. (e) an increasing velocity with the entire loop within the region of the magnetic field. If more than one choice is correct, please indicate all correct choices for the answer. 1) There is no magnetic flux in the loop. 2) The magnetic flux through the loop is increasing. 3) There is an induced emf producing a current in the loop. 4) There is an induced clockwise current in the loop. 5) There is an induced magnetic field within the loop. 6) There is an induced counter-clockwise current in the loop. 7) The magnetic flux through the loop is decreasing. Choose two of the situations above and explain how Lenz's Law and/or Faraday's law is applied in those cases.
