It depends mostly on how strong the magnet is and how much iron, nickel, cobalt is in the substance its supposed to stick to, as these elements are the only common substances that readily stick to magnets, except other magnets or electromagnets. A premium quality, N45 purity neodymium based permanent magnet in the form of a 1 inch x 1 inch x 1 inch cube, for example, can pull a another magnet of the same type several inches away and steel staples as far away as a hand length (the length between the tip of your thumb and the tip of your pinky, with all your fingers spred out). On the other hand, a magnetite refrigerator magnet (about the worst type of magnet there is) would have to be less than half an inch away from steel staples to attract them.
Keep in mind that the actual range of a magnetic field is infinite, but because of the physical properties of such fields, their strength is only noticeable when very close to their source. Therefore, the "significant" range of a magnetic field depends on how strong its source is.
The place in a wave where particles are far apart is called a crest.
When you move the bar magnet far away from the nails, the magnetic field surrounding the magnet weakens significantly. As a result, the magnetic force acting on the nails decreases, causing them to lose their magnetized state and fall off.
When the particles of a wave are far apart, it is in the resting state, or equilibrium position.
It is called diffusion when particles spread far apart and fill all the space available.
The crest of a wave is the part where the molecules are far apart. The crest is the highest point of the wave where the amplitude is at its maximum, causing the molecules to stretch out.
Unfortunately this question needs more detail to answer. Are you asking about how far apart a magnet and a paperclip are if they're touching (# of atoms), or how far apart the magnet at my house is from the paperclip in china, or how far apart a magnet has to be from a paperclip before it starts to create a pull (even this would need more details, what size of magnet, what strength, what size of paperclip)?
Far apart.
An example of a scale would be how much you Weigh now then how much you used to way and a scale can tell you how far apart your weight is now. So technically its something to help you measure things and tell how far apart things are.
Quite far apart I'd say. There is an ocean in between.
how far apart is the untied states from Algeria
The mile is a measure of distance and is used to describe how far places are apart or as part of a description of the speed at which something is moving.
Millions of light-years apart.
The place in a wave where particles are far apart is called a crest.
As far as I know they do not stand out as having done anything special, apart from being called of God to become members of the 12 Apostles.
They are 90 feet apart.
a day apart
32 miles apart.
