Start up the simulation by clicking on https://www.compadre.org/Physlets/electromagnetism/illustration27 1.cfm Starting the simulation: You should see a magnet and a compass at the center of the page: If warned about Java updates, hit the Attempt to view the simulation anyways If a warning states that java script is blocked, click block button "in the upper right to add an exception. Then reload the simulation, and it should start. YOU MAY NEED TO RELODE THE WEB PAGE PERIODICALLY as I noticed that the simulation stalls every once in a while. How to use the simulation: . You should see a magnet and a compass at the center of the page: Testing magnets Begin testing your answers to the questions 2, 3, 4 and 5. Explain how you tested each and what was the result were in the next few questions. Were your predictions for question 2 accurate? Correct B them on the diagram to the right and explain why your predictions were/were not correct: C D A compass placed at C will points (left or right). This means that the north end of a compass points towards the (north or south) end of a magnet. Correct your predictions on the diagram to the right for the other questions below: Question 3 Question 4 Question 5 Correction Correction Correction A D D B C B E A NAN H B E F G DSuppose you had a magnet oriented in the direction indicated below and you wanted to place another magnet to its right. Indicate the North and South poles on the blank magnet as to the orientation that you would give it such that the two magnets would attract: N A 11. What is the direction of the field lines exactly in between the two north poles at pointA? (left, right, or zero). 12. Explain why you think the two magnets would attract using reasoning indicating the directions of the magnetic field lines in between the magnets: The earth has both geographic poles associated with its rotational axis and magnetic poles associated with that fact that the earth is a very large magnet. The two sets of poles are relatively close to each other, but are separated by a few hundred miles. In fact, the magnetic poles move several miles each year. NGP The picture at right shows the location of the north geographic pole (NGP) and the south geographic pole 1 1 (SGP), the two poles associated with the rotation of the earth on its axis. Also shown are the locations of the two magnetic poles. Label the map to show which is the north magnetic pole (NMP) and which is the south magnetic pole (SMP). Draw magnetic field lines about these poles on the diagram just as you did with the earlier magnets. 13. When our compass is pointed towards geographic north (NGP), this indicates that this is actually magnetic (south or north). SGP 14. Explain you answer for question 13 using reasoning indicating the directions of the magnetic field lines in between the poles and what you learned as far as the pole that a compass points towards
