i dont know ,are you in 7se by any chance
Because of the magnetic force
Is iron has to stick to the magnet.
Magnets have a magnetic field about them. This field can act on objects without the magnet coming in contact with the object.
A soft magnet's magnetic field can be broken easily. A hard magnet's magnetic field can not be broken easily.
The volume surrounding a magnet will be filled with the lines of magnetic force. Since these are similarly polarized, they repel each other - eventually creating a sphere at a sufficiently large distance. This sphere is the magnetic field of that magnet.
Magnetic force is inversely proportional to the square of the distance from the magnet which generates it.
Zero - that is, when they are touching. The strength of the magnetic force is inversely proportional to the square of the distance between the magnet and the paper clip.
Magnetic equator.
the closer the magnet is to the nails the greater the magnetic force between the magnet and the nails
The effective length of a magnet is the distance between the magnetic poles. It is always less than the geometric length of the magnet,though the actual relation between the two depends on the shape of the magnet.
Yes, as the distance of the magnet increase its magnetic force decreases
Yes, as the distance of the magnet increase its magnetic force decreases
It remains constant

The voltage would depend on the speed of the magnet. It also depends on other factors, e.g. the angle between the magnetic field lines and the movement, and the strength of the magnetic field at that point.
