GEOLOGY

Detailed explanation-1: -These areas are called the poles of a magnet. A magnetic pole is the part of a magnet that exerts the strongest force on other magnets or magnetic material, such as iron.

Detailed explanation-2: -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-3: -The space around a magnet where its influence can be detected, is called magnetic field.

Detailed explanation-4: -F=ILBsin where is the angle between the wire and the magnetic field. The force is perpendicular to the field and the current. The equivalent formula for the force on a moving charged particle of charge q and velocity v is F, equals, q, v, B, sine, theta, F=qvBsin, with the force perpendicular to field and velocity.

Detailed explanation-5: -We understand that magnets have two poles and that depending on the orientation of two magnets there can be attraction (opposite poles) or repulsion (similar poles). We recognize that there is some region extending around a magnet where this happens. The magnetic field describes this region.
