TRUE STATEMENTS
=> Every electron in an atom behaves like a tiny magnet :
becuase a spinning electron produces a magnetic field that makes the electron behave a like a tiny magnet in a an atom
=>when magnet is broken in half you end up with two smaller magnets :
Breaking a Bar Magnet Breaking a bar magnet produces two pieces of iron whose dipole alignment is identical to the original piece. Both pieces will also be magnets, with N-poles and S-poles at opposite ends. Continued breaking will produce the same results, since the domains within the magnet remain aligned even when the magnet is broken
=> magnetic domains are present even an unmagnetized piece of iron:
In an unmagnetized piece of iron there are millions of these domains, but they are pointing in random directions so that the piece of iron, as a whole, is not magnetized
=> dropping a magnet makes it weaker:
Very simply, all the atoms that make up a magnetic material have a very slight magnetic field.
When this is a magnet - which can be caused, for example, using another magnet, like when a magnet is used on a nail - all these atoms line up and their magnetic fields combine, causing an effect that can be observed and used.
Any action that causes these atoms to lose their line will reduce the magnet's strength - dropping/hitting a magnet and passing a powerful electric current through it are two things that will do this, eventually removing any noticeable magnetism.
=>when two nearby electrons in a material have opposite spins thier contribution to the local magnetic field tend to add up
FALSE STATEMENTS
OPPOSITE POLES WILL NOT REPEL:
Opposite poles attract because they want to stabilize their electron configurations. A stable atom is one that has a neutral force
HEATING A MAGNET MAKES IT WEAKER.NOT STRONGER
Yes one of the easiest ways to make magnet weak is heat; heat is one of the greatest enemies of magnetism
