  2. QUESTION I know magnets affect a compass, but can electric current affect a compass? Menu

  3. HYPOTHESIS We think electricity wouldn´t affect the compass because the compass works by magnet. Menu

  4. MATERIALS • Aluminum foil • Size D battery • Small cereal bowl • Sewing needle • Bar magnet • Water • Small piece of corrugated cardboard • Compass • Camera • Shoebox • Electric tape Menu

  5. PROCEDURE 1.Gather all of the materials. Cut the aluminum foil into a 36 inch strip. Wrap the aluminum strip around the bowl as many times as possible- the first layer going over the top of the bowl. ( leave 15 cm free on both ends of the strip). 2. Magnetize the needle by laying it on the magnet for 2 minutes . 3. Fill the bowl ¾ full of water. 4.Have your teacher help put the magnetized needle through the cardboard piece until it pokes the opposite end of the cardboard. Leave equal length of the needle extending from each side of the cardboard. 5.Float the cardboard square gently on top of the water and let it come to rest. 6.Use the compass to determine what directions the ends of the floating needle are pointing. 7.Turn the bowl to aluminum strips are running in the same direction as the needle, north to south. 8. Stand the flat (negative part) of the battery on one end of the foil. 9.Watch the needle as you touch the other end of the foil to the positive part of the battery. 10.Remove the foil and repeat step 9 a few times.

  8. RESULTSANDCONCLUSION At first the needle pointed north and south. In the middle it didn´t work. At the end the electricity made the needle point east and west. We made a magnetic field so the needle couldn´t point north. Menu
