Why does a magnet's magnetic-field reach out further than that of an atom ?

[unsure]

Why does the magnetic-field of a magnet ( or group of connected atoms ) reach out further than that of a single atom of which the magnet is made of ?

The only explanations I can think of is that maybe when atoms are linked/connected together by atomic bonds, their magnetic-fields are squished out ( like stacking ten cakes together ),     OR,     the magnetic-fields of individual-atoms react against the magnetic-fields of the other individual-atoms with which they have atomic-bonds,  causing an amplification or multiplication of the overall magnetic-field,  due to an unexplained effect,  maybe this is one explanation of unexplained surplus energy that may allow devices to self-power themselves .

It's not 'their' magnetic field.
The magnetic field itself is part of space.
It does not belong to the atom but to the environment it is moving in.
Most people don't understand this, because they are dealing with the invisible.

A visible analogy would be, why does a 100 watt light bulb shine brighter then a 40 watt light bulb ?
The light is not part of the light bulb, the bub only produces the effect.
You can play with a light bulb, your entire life, in the hopes that it will magically light up by itself.
But it's not going to happen and neither are magnets going magically power appliances without any input that can be converted into useful energy.

In the case of the bulb we understand that we need to put in energy in the form of electricity to make it shine.
In the case of the magnetic field we know we have to use motion to convert it into electricity.

So to answer your question, its concentration the magnet acts like a lens it will concentrate the field in the same way you can use a lens to concentrate light in one spot.
100 light bulbs in one spot will shine brighter then 1 light light bulb in one spot.

I can go on, our current means of producing light have long been crude.
We apply so much energy that something heats up and the electrons become looser and they start to jump up and down their valence band releasing photons in the process.
This is a very inefficient way of creating the desired effect, it is brute force, most of the input energy is wasted as heat, it's like trying to repair a swiss watch with a hammer.
BUT is is the EASY way and that is why we found it first and have been using it for well over a 100 years.
There are better ways but they require a different power supply.

Another way to do it is to use a gas discharge lamp.
Less heat and more light the more efficient type of bulbs were of the CFL or high pressure Sodium/Mercury type.

But there is another way, it is also possible to supply energy in phase with it's motion, 'resonance', this is the famous 'kid on the swing' 
The problem exists in generating the necessary frequency to hit the moving target, but we manage to generate 'low' undertones that still resonate at the atomic level, and that are paving the way on how to expand on this method.

It's like evolution really.
You start off with a raw rock and end with up with a diamond.

So i would like to rephrase the question.

Not ' Why does a magnet's magnetic-field reach out further than that of an atom ?'

But: 'How does a magnet's magnetic-field reach out further than that of an atom ?'

Why does the magnetic-field of a magnet ( or group of connected atoms ) reach out further than that of a single atom of which the magnet is made of ?

Each atom is a magnetic dipole, and at distances greater than the dipole dimensions the magnetic field reduces in amplitude following an inverse cube law with respect to distance.  From a single atom the magnitude therefore falls off rapidly with distance, but doesn't reach zero, it just becomes very very small.  Add together the very very small fields from the huge number of atoms in the magnet and the result is not very very small, but something quite significant.  There is no magic in this.
