When the magnet is free to rotate and its poles are in a horizontal plane,
it comes to rest with its poles pointing roughly north and south.
It reacts to the magnetic field of the Earth.

The term magnet comes from a Greek term that means "Magnesian Stone".
A lifting magnet is an electromagnet that is meant to hold or move material that comes in contact with the magnet. This is the opposite of a traction magnet.
The natural magnet is present at the core of our planet earth.
The nail is made of non-polarized iron. and doesn't repel either side of a magnet. A magnet has two poles and will repel another magnet with the same pole (north repels north, south repels south). Since the nail doesn't have a poles it doesn't repel either side.
magnet comes from the word magneto in ancint greek magneto means somthing that can repell please vote for me chioa
Dynamo has constant magnet inside.When movement comes up ,magnet starts turning .And outside of magnet has coiled wire .So this movement of magnet causes electromagnetic effect .Finally current consists with this electomagnetic effect.
It comes from the Bible, Matthew 10:8, in which Jesus says "Heal the sick, cleanse the lepers, raise the dead, cast out devils: freely ye have received, freely give."
A bar magnet, like other magnets, has uses based on its magnetic attraction. This magnetic attraction draws other ferromagnetic materials to it or the bar magnet towards them. These uses include: picking up small ferromagnetic items such as screws and metal shavings; being used as "magnetic stirring rods" on laboratory hotplates; and holding papers and other items to the sides of refrigerators. Like other magnets, the magnetic field generated by a bar magnet can damage electronic equipment. A bar magnet placed near a hard drive, computer disk, or even a video cassette can cause the data stored by the magnetic particles on the item to be damaged. Bar magnets placed on the sides of speakers or other sound devices can cause disruptions in the sound or even permanent damage. A bar magnet placed on the side of a computer can result in the system being deactivated, and may even make it completely inoperable.

Very freely; Newton's law of action and reaction comes into full play.
