1. Lodestone is the first known magnet which was found in Magnesia. It is an ore of iron oxide. The pieces of lodestone found in nature were later categorized as natural magnets. Whereas, there are artificial magnets too which is a magnetised piece of iron or any other magnetic material. These include iron, nickel, cobalt, some alloys of rare-earth metals.

2. Magnets are found everywhere on Earth as it is a mineral.

3. It is inherent property and does not acquire it. 

4. Iron does have magnetic property. Iron is made up of countless tiny bits, all them magnets. Usually, all these little bits are facing randomly, like people crowded in a room. When the iron is made magnetic, all these randomly facing bits align themselves in the sam direction. And this is why an iron piece gets attracted to a magnet.

Plssss answer..... Assertion: Magnetic field lines never intersect each other. Reason: If they intersect, then at the point of intersection, the compass needle would point towards two directions, which is not possible.
