This is because of the polarity of the magnetic field and how north interact with south.
In the middle of the magnet, the magnetic field is sort of neutral.
The further away from middle and the stronger the force will be.
The end of a magnet is called its pole. A magnet has two poles: a north pole and a south pole. These poles are where the magnetic field is strongest and where magnetic forces are generated.
When one end of the unmagnetized needle is in contact with a magnet, the magnetic field from the magnet induces magnetism in the needle. This results in the end of the needle touching the magnet becoming a magnetic pole, and the other end becoming an opposite pole. The opposite poles attract each other, causing the unmagnetized needle to attract another needle when in contact with a magnet.
The end of a magnet that points towards the Earth's Geographic North Pole is labeled as the North Pole of the magnet, while the end that points towards the South Pole is labeled as the South Pole of the magnet.
North Seeking Pole
It is not possible to create a magnet with two south poles or two north poles. Both the poles always exist along with each other. Force 2 magnets together end to end with the south poles together. You will get a north pole at each end and a big south pole in the middle. This arrangement is called a quadrupole.
In the middle because it is in equilibrium.
Using a magnet, string and needle you can create a crude but workable compass. Method Get a needle or a very small nail and a bar magnet. Also get some thread or a bowl of water and two tiny pieces of cork. Hold the needle in one hand and the magnet in the other. Put the North end of the magnet against the needle in the middle and rub it towards and off the point. Lift the magnet up and away from the needle and place it in the middle again. Repeat rubbing the North end of the magnet against one half of the needle 20 times or so. Flip the magnet over so you are using the South end and rub it from the middle to the 'eye' end of the needle 20 times. You have magnetized the needle just like a compass needle. Hanging Compass Tie one end of a length of thread to a stick and the other end to the middle of the needle. Balance is important Let the needle hang freely and slide the thread to a point on the needle where it balances level. Lower the needle into a wide-mouthed jar and lay the stick across the opening to prevent wind interference. Watch which way your compass needle turns. It should always settle to the same direction.
A Yard Stick
Measure the length of the stick and divide that number by 2. For example: If the length of the stick is measured to be 2 meters, then 2 meters / 2 = 1 meter. The middle of the stick can be located by measuring 1 meter from either end of the stick towards the center (middle) of the stick.
Magnets stick together when you have two different poles next to each other. The North end and the South end attract, whereas two of the same poles repel. It is a magnetic force or pull that makes them stick together.
There are not separate north and south magnets; each magnet has both a north end and a south end. These can't be separated. Putting a magnet against a normal (non-magnetized) piece of iron, like the refrigerator, works no matter in what direction (north or south) you put it; the magnetism of the magnet will temporarily induce magnetism in the refrigerator in this case.
The Magnet ended in 1940.
Those are called the poles of the magnet.
Magnet Records ended in 1988.
if you have a magnet and a magnetic matereal, rub the magnet from one end of it to the other. do this several times and it will eventualy be a magnet.
To determine the polarity of a magnet, you can use a compass. The end of the magnet that attracts the north pole of the compass is the magnet's north pole, and the end that attracts the south pole of the compass is the magnet's south pole.
