Question

What is magnetic flux density? Define the unit.

Answer 1

The SI unit for magnetic flux density is called the tesla,................The amount of magnetic flux through a unit area taken perpendicular to the direction of the magnetic flux. Also called magnetic induction.

In physics, specifically electromagnetism, the magnetic flux through a surface is the surface integral of the normal component of the magnetic field B over that surface. It is usually denoted Φ or ΦB. The SI unit of magnetic flux is the weber, and the CGS unit is the maxwell.
