state the characteristics of magneti field line
Answers
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:
characteristics of magnetic field lines are
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.
