Hi,
Is magnetic field affected by metal conductor?
How metal works with electric field, magnetic field, and
electromagnetic field?
Thanks,
SP

Depends on metal. A ferrous metal (like iron) WILL distort field lines.
A non ferrous conductor like copper or aluminum will not affect a
STEADY or DC magnetic field, but because of induction WILL effect an AC
magnetic field.

Curiously, however, it will affect the field in the opposite direction
to the effect of a ferrous metal.
