Answer:
IMAGINARY CONTINUES CLOSED CURVES USED TO REPRESENT THE MAGNETIC FIELD IN A REGION IS KNOWN AS MAGNETIC FIELD LINES.
General Properties of Magnetic Lines of Force
1.They seek the path of least resistance between opposite magnetic poles.
2.They never cross one another.
3.They all have the same strength.
4.Their density decreases (they spread out) when they move from an area of higher permeability to an area of lower permeability.
