What are the two poles on a magnet?

magnet has two poles..one is north pole n the other is south pole. the earth also has a magnet within it which has a dierction opposite to the direction of the geographical poles.i.e. the geographical north of earth is its magnetic south and vice versa. If a bar magnet is suspended freely , its one end is attracted to the magnetic north which is geographical south of earth n therefore that end of the magnet is called south pole.and the other end is called north pole.


Why does freely suspended magnet always point in the same direction?

A freely suspended magnet will always point in the same direction because it aligns itself with the Earth's magnetic field. This causes one end of the magnet to point towards the Earth's magnetic north pole and the other end to point towards the South pole.


What do scrap heap magnets repel?

The strength of any electromagnet changes when the current (amperes) or the number of 'turns' of wire in its wire coil changes. Increasing either of them makes the magnet stronger.


What happens when silver is added to copper sulphate solution?

Reason why it doesnt have a reactions is because both copper and silver are below the reactant leverl. If you look at the Activity Series of Metals on your periodic table, you'll see that copper and silver are below the arrow meaning its least reactant for which when those 2 are mixed no reaction occurs. .....Im not 100% sure though as I am currently learning this in 3U chemistry course...but I hope I helped (:
