Is a nail electromagnet?
Yes, a galvanized nail is still made mostly of iron or steel. The galvanization is merely a coating of zinc.
Will coating a magnet with paint weaken its magnetism?
Not measurably.
How can zinc be separated from lead?
You could submerge the galvanized iron in HCl, which would then dissolve the zinc, at which point you could weigh the iron again to determine the mass of zinc that was removed.
Where can you find information on 1943 zinc-coated steel pennies?
There were over a billion pennies minted in 1943 out of steel coated with zinc. In circulated condition, they'er worth about 5 cents. What you are probably confusing this with is the rare 1943 COPPER penny. A few dozen of these were accidently made in 1943 from old copper blanks. These sell for tens of thousands of dollars. They are also highly counterfeited -- usually by copper plating a steel 1943 cent -- check with a magnet to eliminate 99% of the fakes (a real one will not stick to a magnet).
Does foam affect the strength of a magnet?
Magnetism is the number of magnetic moments per unit of volume, so it is the volume of the magnet that determines magnetism. If an object has great weight and volume, the magnetism will be stronger. If an object has a great weight but lesser volume, the magnetism will be weaker.?æ
Will a magnet stick to galvanized steel?
Yes, a magnet will stick to galvanized steel. Galvanized steel is steel that has been dipped in molten zinc so it comes out with a zinc coating. (The zinc coating inhibits corrosion.) A magnetic can "reach through" this coating and stick to the steel.

Do magnetic trailer lights ground through the magnet?
Magnetic trailer lights have a protective coating on the magnets to keep them from damaging the paint on the vehicle being towed.They also cannot make contact with "ground" through the paint, even if the protective coating was missing.The answer is, no they do not ground through the magnet.
Would you die if you ate a magnet?
The magnet by itself would not kill you. However... If the magnet was sharp or pointy it could cut or perforate your digestive tract, which could kill you. If the magnet was too large to pass through your digestive tract it could cause a fatal obsruction. If the magnet was coated with a toxic substance, that substance could kill you.

How could a student use a magnet to indicate that combining iron an sulfur to produce the mixture of iron and sulfur is a physical change?
A mixture of iron and sulfur can be separated using a magnet- the iron will be attracted to the magnet, sulfur will not. Not the that the iron could be coated with sulfur powder so an extra step is required to remove it.
Why magnet can attract 1 cent coin although it is a non magnetic object?
This is because modern pennies are not entirely copper, they are nickel with a copper coating.
