Magnetic field lines are always nearly normal to the surface of a ferromagnet at every point.Why?

Text Solution

Verified by Experts

Proof of this important fact is based on boundary conditions of magnetic fields `(vecB and vecH)` at the interface of two media (When one of the media has , `mu gt gt ` 1, the field lines meet this medium nearly normally.)

Magnetic field lines are always nearly normal to the surface of a ferromagnet at every point. (This fact is analogous to the static electric field lines being normal to the surface of a conductor at every point.) Why?

Answer the following questions: (a) Why does a paramagnetic sample display greater magnetization (for the same magnetizing field) when cooled. (b) Why is diamagnetism, in contrast, almost independent of temperature? (c) If a toroid uses bismuth for its core, will the field in the core be (slightly) greater or (slightly) less than when the core is empty? (d) Is the permeability of a ferromagnetic material independent of the magnetic field? If not, is it more for lower or higher fields? (e) Magnetic field lines are always nearly normal to the surface of a ferromagnet at every point (This fact is analogous to the static electric field lines being normal to the surface of a conductor at every point). Why? (f) Would the maximum possible magnetization of a paramagnetic sample be of the same order of magnitude as the magnetization of a ferromagnet?

Magnetic field lines determine

A: The magnetic field lines also represent the lines of force on a moving charged particle at every point. R: Force on a moving charge acts parallel to the magnetic field.
