Magnetic lines of forces are very close to each other near the poles and very separated when away from the pole. Why?
Answers
When unlike poles, i.e. the north and the south poles of two magnets are placed close to each other, the magnetic field lines link, causing the magnets to attract each other. ... If you place a strong magnet next to the compass needle, the needle will turn and point towards the north pole of the magnet.The north pole of a magnet will tend to line up with the magnetic field, so a suspended compas needle will rotate until it lines up with the magnetic field. Unlike magnetic poles attract, so the north indicator of the compass will point toward the south pole of a magnet.The field lines are drawn along the direction of the magnetic field and along the direction the iron filings would point. ... The intensity of the magnetic field is represented by the spacing of the magnetic field lines; a strong magnetic field has the lines close together.
magnetic field lines are closer at the poles thereby the force is stronger at the poles.
when they are away from poles, the force is comparatively less strong.
