Want this question answered?
When distance between two magnets decrease, the less magnet force the magnet has.
What happens if vary/change the distance between the magnet and the nail/s?
29.4cm
the magnet gets weaker
The magnetism between the two magnets made the experiment change rappidly.
the closer the magnet is to the nails the greater the magnetic force between the magnet and the nails
It remains constant

What happens if vary/change the distance between the magnet and the nail/s?
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 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.
29.4cm
no
-- While the magnet is moving, there is a voltage between the ends of the coil and, if there's any connection between the ends, then there's a current in the coil. -- When the magnet stops moving, all of that goes away. -- When the magnet is pulled out, it all happens again, but with the opposite polarity.
i dont know ,are you in 7se by any chance
