Get Your Science On: Magnetic Line Dancing

 In Get Your Science On, Shopcasts and Videos

Kayla shows us an awesome experiment to show changing magnetic field lines!

 Materials Needed

Large ceramic magnet
Turntable, Lazy Susan or similar turning device
Iron filing
Non-magnetic container to put iron filings in

What’s Going On?

Iron is a magnetic materials, but it doesn’t stay magnetized. When placed near a strong magnetic, the filings get magnetized and line up with the magnetic field lines. Basically each “spike” becomes it’s own little magnet oriented with it’s north pole facing the south pole of the large magnet. As the large magnet moves, the iron moves as well, trying to keep the same orientation to the magnet.
