Easy Science Project Magnets Experiments For Science Fair
Science Project Ideas Magnets aren't solely helpful tools that are fun to use, they conjointly create wonderful subjects for fast and straightforward science experiments. you'll use magnets found in common home natural philosophy -- and even those who prolong refrigerators -- to demonstrate a number of the foremost fascinating properties of magnetism while not abundant preparation or value.
Nail magnet
Wrap a length of copper wire around associate degree iron nail in order that eight inches of wire is left uncoiled at every finish. Take one finish of the wire and tape it to the positive (+) finish of a AA battery, and tape the opposite finish of the wire to the negative (-) finish of the battery. you'll then use the nail to draw in little metal objects, like paperclips. A record that objects are drawn to the nail and which are not, and that objects were attracted however were too serious. you'll conjointly experiment with larger batteries to visualize however they have an effect on your magnet's strength.
Then, place a gem clip beside the magnet, on the ruler's same edge and aligned with the 2-inch line. If the gem clip attracts toward the magnet, move the gem clip back a half-inch. still, move the gem clip either nearer or farther off from the magnet - on the ruler's edge - to seek out the gap at that the gem clip is not any longer attracted, so live that distance on the ruler.
The Simplest Motor
Set the top of a drywall screw onto the flat facet of a metallic element disc Magnet in order that the screw stands straight up. Then bend a chunk of copper wire thus you'll simply bite it to each end of the motor you may build. Lower the positive (+) finish of a battery to the highest of the screw till the tip of the screw attaches itself to the battery. elevate the whole device rigorously. bit one finish of the wire to the negative (-) finish of the battery, and use a finger to carry it in situ. bit the opposite finish to the sting of the disc magnet. once the wire makes contact with each the battery and therefore the magnet, the electrical charge moves radially on the magnet's axis.
