GEOLOGY

Detailed explanation-1: -The magnetic field is the area around a magnet that has magnetic force. All magnets have north and south poles . Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction.

Detailed explanation-2: -The space around a magnet where the magnetic force acts is called the magnetic field (just as the space around a mass where the gravitational force acts is called a gravitational field).

Detailed explanation-3: -A magnet is any object that produces its own magnetic field that interacts with other magnetic fields. Magnets have two poles, a north pole and a south pole. The magnetic field is represented by field lines that start at a magnet’s north pole and end at the south pole.

Detailed explanation-4: -Review: The magnetic lines of force, indicate the region in which the force of the magnet can be detected. This region is called the magnetic field. The magnetic lines of force, or flux, leave the north pole and enter the south pole.

Detailed explanation-5: -Magnetic fields are everywhere Naturally occurring magnetic fields are seen everywhere in the universe. They were first observed on Earth thousands of years ago, through their interaction with magnetized minerals like lodestone, and used for navigation long before people had any understanding of their nature or origin.
