Detailed explanation-1: -Magnetic field lines are a visual representation of the invisible lines of force in a magnetic field. By convention, the lines trace the force from the north to south pole of a magnet. The distance between the lines indicates relative strength of 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: -The invisible area around a magnetic object that can pull another magnetic object toward it or push another magnetic object away from it is called a magnetic field.
Detailed explanation-4: -The two ends, called the magnetic poles, are where the force is strongest. A magnetic field of force is set up between the two poles. You can think of it as invisible lines of force traveling from one pole to the other. The magnetic lines (flux lines) are continuous and always form loops.
Detailed explanation-5: -The field represents the object generating it. Gravitational fields map gravitational forces, electric fields map electrical forces, and magnetic fields map magnetic forces.
