A bar magnet (or any other kind of magnet) does not work on a microscopic scale. It works on an atomic scale. Let's review atomic structure very briefly. Then we'll hit the nail on the head with an answer. An atom is composed of protons and neutrons (H1 excepted) in a nucleus and an electron (H1) or electrons in orbitals around that nucleus. (Neutral atoms for this one....) In certain types of atoms, the atom's net electron motion makes that atom into an "atomic magnet" with a north and south pole. In magnetic materials that are not magnetized, the "atomic magnets" are all randomly aligned. In a magnet, groups of atoms in a small are (far less than microscopic) get aligned into what are called magnetic domains. Enough alignment of the domains gives an overall net magnet effect to the material, and it becomes a magnet. Got links if you want them. They're to our friends at Wikipedia, where they post knowledge for free.

Why the attraction is zero at the middle of a bar magnet?
Conservation of energy. Attraction is a force, force is zero at conservation of energy.The forces inside the bar magnet configure themselves spatially to conserve energy. The middle of the bar is also an inflection point for energy.
What are the forces between a charge and a bar magnet?
The forces between a charge and a bar magnet are due to the interaction of electric and magnetic fields. Charges create electric fields, while magnets create magnetic fields. When a charge interacts with a bar magnet, the electric and magnetic fields can exert forces on each other, leading to attraction or repulsion between the charge and the magnet.
Why does the needle of a compass point south when it's put on a bar magnet?
When a compass needle is placed near a bar magnet, it aligns itself with the magnetic field created by the magnet. The compass needle is a small magnet itself, with its north pole attracted to the south pole of the bar magnet and repelled by its north pole. If the compass needle points south, it indicates that the bar magnet's south pole is near the compass's north pole, demonstrating the fundamental property of magnetic attraction and repulsion. Thus, the orientation of the compass needle reflects the magnetic field direction of the bar magnet.
How does a bar magnet interact with a compass?
A bar magnet interacts with a compass by aligning the compass needle along the magnetic field lines of the magnet. This causes the compass needle to point towards the North Pole of the magnet, allowing the compass to indicate the direction of the magnetic field.
What location could you place the south pole of a var magnet so that it would be pulled toward the magnet shown?
To attract the south pole of a bar magnet, you would need to place it near the north pole of another magnet or in close proximity to the bar magnet's north pole. Since opposite poles attract, positioning the south pole of the bar magnet toward the north pole of the magnet shown will result in a pull toward the magnet. This attraction occurs because magnetic fields interact in such a way that opposite poles draw closer together.
Is there a scale for magnet strength?
They are bar magnet ,horse shoe magnet ,lime stone magnet.
Is bar magnet a natural magnet?
no
What happens to the bar magnet as it nears the U magnet the bar magnet will?
Move towards the U magnet so that the poles attach.
The use of bar magnet in chemistry?
The magnet bar is used for stirring solutions.
How is an electromagnet different a bar magnet?
a electromagnet is bigger than a bar magnet
What happens to aluminium bar as it moves closer to the magnet?
As the aluminum bar moves closer to the magnet, no magnetic attraction or repulsion is observed. This is because aluminum is not a magnetic material and does not interact with magnetic fields in the same way as ferromagnetic materials like iron or nickel.
Is a magnet?
Yes, a bar magnet is magnetic.
