Need help with a few lab questions please

Part 1: Field from a bar magnet Download the simulation from https://phet.colorado.edu/en/simulation/generator You will need to run this as a java application on your laptop. Make sure that you have the latest version of java. If you have a Mac, use control-click and select Jar launcher to open the file. After opening the simulation, click on the Bar Magnet tab (upper left). You will see a bar magnet and a compass. The standard coloring of any magnet (including the compass) is that the red end is the North pole (N), and the white end is the South pole (S). The small compass symbols in the background give the direction of the magnetic field due to the bar magnet. By definition, the direction of the magnetic field, B, at any location is the direction that the north end of a compass points when placed at that location.1. Observe the behavior of the compass as you move it around the magnet. In the space below, draw an arrow at each numbered location to indicate the direction and the relative strength of the magnetic eld. Write a few sentences explaining how you chose the length and orientation of each arrow. 2. Click on the \"Show Field Meter" option (and uncheck the Compass). A gauge pops up that measures the field at the place where its crosshairs intersect. It provides four values. Explain what each value corresponds to. Why you only need two of these values? Use vector math to show how two of the values can be obtained from the other two. 3. Answer each of the following by using the B eld guage and writing down measurements to support your answer. a. Where is the magnetic eld strongest outside the bar magnet? b. How can you tell if the probe is just inside or outside the magnet? Describe your observations. Part 2: Lenz's Law and Induction Information Magnetic fields are produced by moving charges (electric current) and electric currents can be produced by changing magnetic fields. According to the Right-Hand Rule (RHR), if you point the thumb of your right hand in the direction of a current, your fingers will curl in the direction of the B field. See Figs. 22.16 and 22.38 in the text. To represent a vector field that is perpendicular to a sheet of paper, draw dots if the field points out of the page, and use the 'x' symbol if the field points into the page. (also shown in Fig. 22.16) Tasks 4. The figure below shows two current loops; think of them a wire bent in the shape of a circle that is carying an electric current in the direction shown by the arrow. Use the RHR to determine which direction the magnetic field is pointing inside the loop (is it the same direction everywhere within the loop?). Draw arrows, dots, or Xes inside each loop, as appropriate. Explain your choices. Explain: 5. Click the Electromagnet tab in the simulation. You'll see loops of a wire carrying a current. Decrease the number of loops to one. Explore what happens as you adjust the voltage on the battery. Use the RHR and the definition of electric current to verify that the simulation is showing negative charges moving in the wire. (Are these particles moving in the direction of the current?)6. Slide the voltage back to +10V and click on the eld meter. Do a simple experiment to determine how the strength of the magnetic eld depends on the number of loops in the coil. Does the result depend on the location of the meter? Insert a table showing your measurements. Summarize your conclusions. 7. According to Lenz'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 or 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
