1. The problem statement, all variables and given/known data Question 1- Magnetized Ship You are standing on a shore beside a shimmering blue sea. You will go on a sea expedition to Magnesia and claim the lost treasure of Magnesia. Magnesia is an island which lies near the Antarctica. The only way to get there is by sea. The ship that is given to you is a giant ship but the propulsion system is out of order. Someone suggested magnetziing the ship so that it has a south seeking magnetic pole. The ship will then naturally move along the Earth's magnetic field. Too bad the idea won't work. Can you explain why? (3 Marks) Question 2- Mysterious Cutlery Luckily someone reapirs the propulsion system and now you can begin your expedition. The ship has been moving speedily and steadily. Unexpectedly storm clouds begin to gather ominously and lightning can be seen flashing incessantly. You turn your attention to the dark sky and before you know it, a huge lightning bolt strikes your ship. Initially, everything on the ship seems to have been unaffected. That is, until you have your meal and discover the spoon and knife attracted to your braces. You vividly remember the cutlery layout and seeing the lightning bolt strike the fork. But the fork isnt magnetized! Instead its the spoon and knife which are mangetized, with the handles having reversed polarities." Discuss why steel cutleries arranged in certain orientations are or are not magnetized by a huge electrical current. (4 marks) Question 3- Magnesia's Treasure You finally reach Magnesia, safe and sane at night. The surrounding is pitch dark and you are told that the entrance to the treasure lies Northward. Fortuitiously, you have in your pockets, a bare piece of copper wire, a flashlight, a dry cell and a compass. But the paint on the compass has faded and you can't tell the poles apart. Discuss without the Sun as a reference. How can you determine the poles of the compass? (4 Marks) 2. Relevant equations 3. The attempt at a solution I have solved question 3 and 1 roughly, but have trouble with question 2. Oh, and we have to use diagrams to solve as well. Question 1 is just that the ship will have a north seeking magnetic pole as well, as all magnets have two poles. Both poles would be influenced by the Earth's Magnetic field and the net result is that it does not move along the Earth's magnetic field. It is 3 marks though, i do not know if i have enough points there. I don't have diagrams for this one though. Question 3 i just used the plotting compass method, and Maxwells Corkscrew rule and the right hand rule to deduce that if the current goes down the wire, a clockwise magnetic field is formed. I would run the current down the wire and place the compass nearby to find out which end of the needle is north, from there finding out the rest. I have already got diagrams for this one. Question 2 I am not quite sure how to do. I think orientation basicalyl means which direction it is facing or something. I guess the spoon and knife have reversed polarities as they are facing different directions? Not much idea about the rest of it though. When you help me, please help me think of diagrams that I could use too.
