Need help with a few physics lab questions please.

7. According to Lcnz's Law, if the magnetic eld enclosed by a loop of wire is changing, a current will be produced in the wire. The direction of the current will be the one that creates a magnetic eld opposite the change in the eld. The wire loops below surround a magnetic eld indicated by the dots er Xes. For each loop, draw an arrow showing the direction of the induced current if the B eld is increasing in strength. Explain the reasoning for your choice of current direction. Explain: 8. Start up a different simulation that will run in your browser: https://phet.colorado.edu/sims/html/faradayslaw/latest/faradayslaw_en.html You will see a magnet and a circuit with four loops of wire connected to a light bulb and a voltmeter. 9. Position the magnet so that it is in the center of the coil. You'll notice that the light bulb ashes briey as you do this. 10. Check the box for magnetic eld lines. Notice the direction of the B eld inside the coil. 11. Based on your answers to step 7 above, make a prediction about what the voltmeter will do when you move the magnet to the right. Provide a step-bystep explanation of the reasoning justifying your prediction. Some things you will need to consider: 0 how the B-eld will change as the magnet moves 0 the direction of the induced current (clockwise or counterclockwise) 0 how the voltage depends on whether the current ows into, or out of, the + terminal 12. What if the magnet is moved to the left, instead? Briey explain how this affects your prediction. 13. Test your predictions by moving the magnet slowly and steadily to the right. Repeat as needed to conrm your observation, then try moving the magnet to the left. Describe what happened in both cases. If the observation is different from your prediction, identify one or more corrections to your reasoning
