Please answer SITUATION 3, 4 and 5.

Instructions are provided in the picture.

Thank you!!

IV. LENZ'S LAW A loop of wire is moved from the before situation to the after situation. The "dots" and "x's" in the background represent the direction (“dots" represent out of the page and "x's" represent into the page) and the strength of the external magnetic field. This was discussed in the USLEM. Determine what will happen to these quantities because of the "changes" that occurred. Select your answers from the given options. Write them in the box. Quantity AOB, change in magnetic flux Binduced the direction of induced magnetic field ɛ the direction of induced emf Options Decreases Increases No change non-existent into the page out of the page clockwise counterclockwise zero • BEFORE AFTER EXAMPLE AOB = decreases Bnduced = out of the page ɛ = counterclockwise Explanation: Initially the magnetic flux is out of the page. But it decreases and the direction of the "change" is into the page. Therefore the Binduced must be in the opposite direction according to Lenz's law. Using the right-hand rule, your curled finger is pointing counterclockwise on the loop of wire.
