GEOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -Magnetic field lines are invisible lines that map out the magnetic field around a magnet. Magnetic field lines spread out from one pole, curve around the magnet, and return to the other pole. The lines form complete loops from pole to pole and never cross.

Detailed explanation-3: -Two opposite poles will attract each other, and two poles that are the same (two north poles or two south poles) will push apart. Although the magnetic field is invisible, it can be seen indirectly. Iron filings placed in the magnetic field will show where the lines of force lie.

Detailed explanation-4: -The magnetic field lines do not intersect.

Detailed explanation-5: -Expert-Verified Answer The statement “Magnetic lines of force are invisible” is true. Explanation: A magnetic field is an area around a magnet or a magnetic object. The magnetic field lines are imaginary lines that represent the direction of the magnetic field.
