If the beam is bent upwards by the action of the magnet it will be bent downwards if the magnet pole is reversed and applied in the same place as before.
It's possible. Striking a permanent magnet can jumble the orientation of the magnetic domains, resulting in a loss of strength.
The nail is made of non-polarized iron. and doesn't repel either side of a magnet. A magnet has two poles and will repel another magnet with the same pole (north repels north, south repels south). Since the nail doesn't have a poles it doesn't repel either side.
a magnet is a solid so you don't freeze it
If the temperature gets higher than a limit (I think it is called Curie temperature) then the fundamental pagentic dipoles loose their orientation and the magnet looses its magnetic field.
the metal object becomes a temporary magnet
It depends on what silver it is!!CorrectionNo. Silver does not have the right atomic orientation to stick to a magnet.
I dunno if I'm right but I think it is called electrons. I mean, electrons were in cathode Rays and were bent by a magnet right?
the ray has a negative charge
Reverse the polarity of armature windings of the motor.

It doesn't matter on the orientation, it is the attraction of the magnet to pull the contact and complete the circuit that matters.
the magnet gets weaker
it was deflected by a magnet
You have the situation reversed. Like poles repel, opposite poles attrect
Magnetism is produced through electric currents. In the case of a permanent magnet, it is the electrons circling around the atomic nucleus that produces the magnetism (more atoms have one orientation than the opposite orientation).Magnetism is produced through electric currents.

Thomson observed that a cathode ray bent when in the presence of a magnetic field. After the cathode ray bent the opposite way when the opposite pole of the magnet was placed next to it, Thomson concluded that the cathode ray had a negative charge.
Move towards the U magnet so that the poles attach.
