the voltage increases
When a magnet is inserted into a coil, the magnetic field creates a voltage impulse in the coil due to electromagnetic induction. As the magnet is withdrawn, the voltage impulse will reverse in direction. This process is the basis for generating electricity in devices like generators and is used in various applications such as magnetic sensors and magnetic levitation systems.
The compass needle would be affected by the magnetic field from the nearby magnet. The needle would align itself with the magnetic field of the magnet, causing the compass to point in a direction different from true north.
No, water is not magnetic so it would not be affected by a magnet in the same way a charged comb would attract water. The magnetic field from the magnet would not have any significant impact on the water itself.
nothing will happen dumbazz because it isnt magnetic
Rubbing a needle back and forth on a magnet would align the magnetic domains within the needle, causing it to become magnetized. The needle would then exhibit magnetic properties and attract items such as paper clips or iron filings.

It falls.
it would get a lot of voltage
the magnet will repel
That depends on the direction in which the coil of wire is wound.
it loses its magnetic properties
This would only happen if resistance was increasing faster than the rise in voltage.
I don't see any sketch. But if you break a magnet in two, each part will be a magnet with its own north and south pole.
I would expect a voltage in both coils of wire.Note that, if the two coils are connected, the voltages (and corresponding currents) in the coils can interact. Also, if the two coils are NOT connected, they can STILL interact, since a current will produce its own magnetic field.

A current would be induced in the coil.
