Question

state the chartaristic of magnetic field line​

Answer 1

Answer:

Magnetic fields can be pictorially represented by magnetic field lines, the properties of which are as follows:

The field is tangent to the magnetic field line.

Field strength is proportional to the line density.

Field lines cannot cross.

Field lines are continuous loops.

Answer 2

Answer:

General Properties of Magnetic Lines of Force

They seek the path of least resistance between opposite magnetic poles. ... 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.
