Here's why:

* Nickel Composition: Canadian nickels minted after 1962 are made of a nickel-copper alloy. This alloy is non-magnetic.

* Magnetic Materials: Magnets attract ferromagnetic materials like iron, cobalt, and nickel. However, the nickel in the coin is alloyed with copper, making it less magnetic than pure nickel.

Therefore, a 1982 Canadian nickel should not stick to a magnet. If it does, there might be another magnetic object near the nickel, or the coin itself might be a fake.
