Why Do Broken magnets repel each other?
They repel because after cutting them into two ,they become two independent magnets.
When they were one inside the earlier magnet, even then they opposed each other.
But they remained as magnets because coercive force held them together..

Why does dropping a magnet weaken it?
Permanent magnets can lose their magnetism if they are dropped or banged on enough to bump their domains out of alignment. … The reason that would be hard to bump a piece of iron and make it magnetic is because of the way vibrations propagate in the material.
Are stacked magnets more powerful?
By adding one magnet on to the other, e.g. stacking, the stacked magnets will work as one bigger magnet and will exert a greater magnetic performance. As more magnets are stacked together, the strength will increase until the length of the stack is equal to the diameter.
What happens when 2 magnets come together?
When two magnets are brought together, the opposite poles will attract one another, but the like poles will repel one another. This is similar to electric charges.
Do two magnets repel each other?
Every magnet has both a north and a south pole. … When you place like poles of two magnets near each other (north to north or south to south), they will repel each other.
Can a magnet that has lost its strength be re magnetized?
It is possible to re-magnetize a magnet that has lost its magnetic properties, but as long as the alignment of its internal particles has not been modified for any reason, such as, for example, the exposure of these elements to high temperatures.
What is the force between 2 magnets?
The simplest example of this is the attraction of opposite poles of two magnets. Every magnet produces a magnetic field that is stronger near its poles. If opposite poles of two separate magnets are facing each other, each of the magnets are drawn into the stronger magnetic field near the pole of the other.
What causes magnets to attract and repel each other?
Opposites attract. To explain why magnets repel each other, a north end of a magnetic will be attracted to the south of another magnetic. The north and north ends of two magnets as well as the south and south ends of two magnets will repel one another.
How can you make a magnet more powerful?
If you can find a very strong magnet, repeatedly rub it across your weakened magnet. The strong magnet will realign the magnetic domains inside the weakened magnet [source: Luminaltech]. Magnet stacking One way to make weak magnets stronger is by stacking more of them together.
Can I cut magnets?
You can cut the magnet with a saw, following the line of cut, but you can also use a diamond-plated cutter in a lathe and, once placed, press it in place. … Try not to put too much pressure on the lathe or you can bend the cutter. You can also use a chisel on the line of cut that you have made on the magnet.
What happens if a magnet is cut in half?
You can think of a magnet as a bundle of tiny magnets, called magnetic domains, that are jammed together. Each one reinforces the magnetic fields of the others. Each one has a tiny north and south pole. If you cut one in half, the newly cut faces will become the new north or south poles of the smaller pieces.
Can you increase the power of a magnet?
The strength of an electromagnet can be increased by increasing the number of loops of wire around the iron core and by increasing the current or voltage. You can make a temporary magnet by stroking a piece of iron or steel (such as a needle) along a permanent magnet.
Can a magnet pick up copper?
If you have a strong enough magnetic field all matter is magnetic. But copper is so weakly magnetic that we can’t observe it without very, very large magnetic fields. So the short answer is “No, copper isn’t magnetic.” This can quickly be tested by trying to pick up a penny with a magnet.
What is the biggest magnet on Earth?
The biggest magnet on the planet is the earth itself. The earth consists of a relatively shallow crust atop a thick, rocky mantle. Under the mantle is a dense core of liquid metal (mostly iron) surrounding a solid-metal center.
What kind of magnet can be turned on and off?
An electromagnet is a magnet that works with electricity. It can be switched on and off. The coils are nearly always made of copper wire because copper is such an excellent electrical conductor. Electromagnets have many uses.
Do permanent magnets last forever?
So how long should my permanent magnet last? Your permanent magnet should lose no more than 1% of its magnetic strength over a period of 100 years provided it is specified and cared for properly. There are a few things that may cause your magnet to lose its strength: HEAT.
How much force does a magnet exert?
For example, a single D82 (1/2″ diameter x 1/8″ thick) disc magnet has a Pull Force, Case 1 of 6.44 lb. When tested between two steel plates, however, the force required to separate them jumps up to 16 lb!
