Question

What is magnetic flux density and it's unit?

Answer 1

Magnetic flux density:

1. Magnetic flux density(B) is defined as the force acting per unit current per unit length on a wire placed at right angles to the magnetic field.
2. It is a vector quantity.
3. Magnetic flux is denoted by “B”.
4. The SI unit is $\mathrm{Tesla}\left(\mathrm{T}\right)$ or ${\mathrm{Kgs}}^{-2}{\mathrm{A}}^{-1}$.

Mathematically, this can be represented as:

$\mathrm{B}=\frac{\mathrm{F}}{\mathrm{IL}}$

Here,

L is the wire's length.

F is the total force acting.

I is the current flowing.
