GEOLOGY

Detailed explanation-1: -Answer: A force that acts at a distance and cannot be seen. Materials that create this force are said to be magnetic and are called magnets. the poles to attract, and the magnets pull toward each other. The closer the objects, the greater the magnetic force.

Detailed explanation-2: -The magnetic force is one which acts-at-a-distance . 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: -MAGNETISM is the ability of an object to push or pull on another object that has magnetic properties. Magnetic force acts at a DISTANCE and cannot be SEEN.

Detailed explanation-4: -Magnetism is a fascinating invisible force – it influences the environment around it. A magnet is a material that can pull certain types of metal towards itself. Unlike many other forces, magnetism doesn’t have to touch the objects it affects. Gravity is also an invisible force that acts at a distance.

Detailed explanation-5: -Magnetic forces are non contact forces; they pull or push on objects without touching them. Magnets are only attracted to a few ‘magnetic’ metals and not all matter. Magnets are attracted to and repel other magnets.
