One can take a piece of iron that is non-magnetic & with a magnet can induce it to become a magnet. The same is achievable by inserting the iron inside an electric coil called"Solenoid" & switch current from a battery that would make it a magnet. This is the artificial method.Natural magnets abound in nature. Magnetite (Fe₃O₃) ore of Iron is one. These ores are there on Earth for billions of years before Life formed on Earth & far more earlier than Man evolved. Each piece in it has its magnetic domain that might be different from the neighbour domains. Whole effect (result) is that in a chunk of that ore, the domains cancel out each other with aminimal or feeble residuary magnetism for us to notice it.However some ancient men noticed that two such pieces attracteach other. The Greeks must have named it "magnetism" & these were natural magnets. It seems whole hills of natural magnets near a shore, that obviously have a million tonnes of Magnetite ore might even pull a ship (though not drag it to the shore). It might be a tall story but they definitely affected the magnetic compass on thew ship to swing east or westward rather thanshowing true north. It is reported that such instances were there on the coast of Odisha state in India (even a temple dedicated to Sun God had that influence) where there areabundant Iron ores.
