Magnetic Spinning Coin
(Magnetic Spinning Coin Toy)
Take a magnet and place a steel coin (such as an Indian ₹1 coin) on top of it. Now take a pen and remove its refill. Using the back end of the empty pen body, blow air quickly onto the coin placed on the magnet.
As soon as you blow air, the coin starts spinning, but it does not fall down. This happens because the magnet keeps attracting the coin towards itself. The magnetic force holds the coin while the air force makes it rotate.
This is a simple, safe, and interesting scientific toy. Through this activity, children learn how a magnet attracts metal and how magnetic force works. It increases curiosity and helps students understand science in a fun way
