Unformatted text preview: create a magnetic flux to oppose the change in magnetic flux through the loop. 1 9 a. Magnet moves toward loop. Magnet field is down and increasing. Induced emf and thus current will be ccw to oppose the increase. 2 0 b. Magnet moves away from loop. Magnetic field is up and but decreasing. Induced current gives magnetic field to oppose the decrease. 2 1 Motional emf dx 2 2 In time dt the rod will move dx. The area covered in dt will be Faraday’s Law 2 3 A conducting rod moving in a magnetic field will have an emf Ind...
