Question

Answer the following Questions:
Write the characteristic of magnetic field lines.

Answer 1

Characteristics of magnetic field lines are :

• They never cross each other.
• Their density decreases 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 flow from the south pole to the north pole within the material and north pole to south pole outside.
• The tangent to the magnetic field lines at any point gives the direction of the magnetic field at that point
