Question

question 4 of 10
which of these will not stick to a magnet?
choose one option
a a penny
b a paper clip
c another magnet
d a scrap of iron

Explanation:

Magnets attract ferromagnetic materials (like iron, nickel, cobalt). A paper clip (usually steel, ferromagnetic), another magnet (magnets attract each other), and iron scrap are attracted. A penny (US pennies are copper - plated zinc, neither copper nor zinc are ferromagnetic in typical penny composition) does not stick.

Answer:

A. A penny
