A magnet
There's no such thing as a "first magnet". Natural magnets have been around since essentially the big bang.
when a magnet is hardly rubbed on a iron ,for some time it reacts as a magnet. An example of a temporary magnet is used in acar breakers yeard . A crane fitted with amagnet picks up a car and then the power to the magnet is cut and the car drops.
A neodymium magnet is known for its strong magnetism that can last for a long time. These magnets are made of rare earth elements and are commonly used in various applications where a strong, long-lasting magnetic field is required.
Any time a magnet passes through a coil of copper wire (the electro magnet) it produces electricity. In all reallity, you don't really have an electro magnet in a generator. Since the Coil or(field) is making the electricity instead of using electricity, the electro magnet isn't really a magnet; but more like an "anti-magnet" :)
small magnet used to give direction
'Magnet was first found one island named magnetia in Greece
A magnetic substance can also be made into a magnet by aligning its magnetic domains in the same direction. This alignment creates a magnetic field around the substance, allowing it to attract or repel other magnetic materials. The strength of the magnet depends on the material and the alignment of its domains.
what is a keeper used for
Magnet sticks to another magnet when north pole of the first magnet approaches the south pole of the second magnet.
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.
A shepherd from Crete named Magnes was the one to find the magnet. The magnet was found in 600 B.C.
