Question

Is magnetic field inside a conductor , zero?plz explain?

Answer 1

in an ideal conductor its zero

but not practically

Answer 2

Yes, it is inside the conductor.

A ring drawn concentrically inside the conductor, if encloses current (I) then magnetic field (H) exists. if ring has a radius 'r' so that the circumference is l =(2pi r):

I = Closed Integral [H. dl] = 2pi r H

following 'Stokes' theorem that states the line (closed) integral

is the 'curl' of the surface integral.

H as you can see varies with 'r'.

Answer 3

well u have got it wrong................

its electric fiel tht is zero nt the magnetic field.........

Answer 4

Perhaps you're thinking of an electrostatic field inside a conductor being zero (the conductor is known as a Faraday cage).

If you already know this, and you're asking specifically about magnetic fields, then I don't know... I'll star this question myself :)

Answer 5

no it's not zero, Because the magnatic field lines can penetrate the metal...
