They seek the path of least resistance between opposite magnetic poles. In a single bar magnet as shown to the right, they attempt to form closed loops from pole to pole.They never cross one another.They all have the same strength.Their density decreases (they spread out) when they move from an area of higher permeability to an area of lower permeability.Their density decreases with increasing distance from the poles.They are considered to have direction as if flowing, though no actual movement occurs.They flow from the south pole to the north pole within a material and north pole to south pole in air.

1. The don't form closed loops.
2. They are closely packed in a strong electric field region and father apart in week electric field region.
3. The lines never intersect with each other.
4. These are imaginary lines which shows pictorial influence of electric field intensity in space.
5. They are always emitted from positive charge and enter a negative charge.
