Hooked on Science - Magnetic Money

January 6th – January 12th

INGREDIENTS

• Neodymium Magnet

• United States Dollar Bill

INSTRUCTIONS

STEP 1: Hold the dollar bill so it hangs freely from your fingers. What effect will the neodymium magnet have on the dollar bill?

STEP 2: Look for a location on the dollar bill, which has a lot of ink, bring the neodymium magnet close to the dollar bill, and observe. What happens? Apply what you know to design a way to help a cashier determine if money is counterfeit.

EXPLANATION

To prevent counterfeiting, dollar bills in the United States are printed with magnetic ink, which causes the dollar bill to attract to the neodymium magnet.

SCIENCE SAFETY

PLEASE follow these safety precautions when doing any science experiment.

• ALWAYS have an adult present.

• ALWAYS wear the correct safety gear while doing any experiment.

• NEVER eat or drink anything while doing any experiment.

• REMEMBER experiments may require marbles, small balls, balloons, and other small parts. Those objects could become a CHOKING HAZARD. Adults are to perform those experiments using these objects. Any child can choke or suffocate on uninflated or broken balloons. Keep uninflated or broken balloons away from children.
