Even though it contains Nickel (Ni), a ferromagnetic material, they aren’t visibly attracted to magnets. In fact, they don’t interact with magnets like many other non-magnetic materials. … This is odd because dimes are quarters are both about 92% Cu and 8% Ni – not too different than Nickel (the coin).
Why are coins not magnetic?
While nickel is also magnetic, there isn’t enough nickel in standard United States coins to make them magnetic.

Can you pick up a nickel with a magnet?
The element Nickel (Ni) is one of the few ferromagnetic metals. Ferromagnetic means they are attracted to magnets and can be magnetized themselves. Most metals aren’t magnetic with the exception of iron, nickel, cobalt, gadolinium, neodymium and samarium.
Is a 1 coin magnetic?
The ‘Copper’ 1p and 2p coins were traditionally made from a bronze alloy of copper, tin and zinc. However, since September 1992 they have been made from copper-plated steel. … The iron content in the steel core is what makes them magnetic.
Does aluminum foil attract magnets?
In our everyday experience aluminum doesn’t stick to magnets (neither does copper). The question of whether aluminum is magnetic is a bit more involved and depends what you mean by the term “magnetic”. Most matter will exhibit some magnetic attraction when under high enough magnetic fields.
Which Pennies are magnetic?

Does a magnet stick to Pewter?
NO. Pewter is a malleable metal alloy, traditionally 85 -95% Tin, with the remainder consisting of Copper, Antimony, Bismuth and sometimes, less commonly today, Lead. Silver is also sometimes used.
