Solution

The correct option is A True
Answer is A.

The lines that are mapped out around the magnet, called 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. If an iron object is brought near a magnet, but is not within the magnetic field, the object will not be attracted to the magnet. When the object enters the magnetic field, the force of the magnet acts, and the object is attracted. The pattern of these lines of force tells us something about the characteristics of the forces caused by the magnet. The magnetic lines of force, or flux, leave the north pole and enter the south pole. That is, the magnetic lines of force extend from the North pole of the bar magnet to the South pole of the bar magnet externally and from south pole to north pole internally.
