Concept questions. Be ready to give answers and explanations when called by table number. Consider the loop moving towards the magnet as shown. Is the external field passing through the loop increasing or decreasing? && As the loop moves towards the magnet, the magnetic field lines passing through the loop increase. This is because the loop is getting closer to the magnet, where the magnetic field is stronger. Therefore, the external field passing through the loop is increasing. Is the induced field in the same direction as the applied field or the opposite direction? && The induced field is in the opposite direction to the applied field. This is due to Lenz's Law, which states that the induced electromagnetic field always opposes the change in the magnetic field that produced it. Therefore, if the applied magnetic field is increasing, the induced field will work to reduce this increase. What is the direction of the magnetic moment induced in the loop? &&
