Purpose The purpose of this experiment is to determine whether the strength of the magnetic field created by 5 magnets is quintuple the strength of the magnetic field created by using only 3 and 4 magnets. This determines if the pencil balances (and spins) in the middle of the metal pole. Materials Pencil Coin 5 Chopsticks or wood sticks Cardboard Super Glue 6 ring magnets Scissors Cutter Ruler or Protractor compass Methods Step#1 Sharpen the tail of the pencil to make it fit into the magnet's hole.
Step#2 Carefully slide one ring magnet on to the pencil and measure the distance from the tip of the pencil to the point where the magnet remains. Use that measurement as a guide to cut the chopsticks in order to make the pole. Step#3 Every magnet has both a North and a South pole. When you place the North pole of one magnet near the South pole of another magnet, they are attracted to one another. When you place like poles of two magnets near each other (North to North or South to South), they will repel each other. In

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
