Question

define magnetice flux .it SI unit

Answer 1

In physics, specifically electromagnetism, the magnetic flux (often denoted Φ or ΦB) through a surface is the surface integral of the normal component of the magnetic field B passing through that surface. The SI unit of magnetic flux is the weber (Wb) (in derived units: volt-seconds), and the CGS unit is the maxwell.

Answer 2

" the total number of magnetic lines of force passing through any surface placed perpendicular to field is called magnetic flux"
S.I unit:Nm/A which is also called Weber
