Unit of magnetic flux density (or magnetic induction) is

The unit of magnetic flux density, also known as magnetic induction, is crucial in electromagnetism. Magnetic flux density represents the amount of magnetic flux passing through a unit area perpendicular to the direction of the magnetic field.

SI Unit of Magnetic Flux Density

In the International System of Units (SI), the unit of magnetic flux density is the tesla (T). This can be derived as:

• B = Magnetic flux density
• Φ = Magnetic flux, measured in webers (Wb)
• ΔA = Area, measured in square meters (m²)

Thus, the unit of magnetic flux density can be expressed as:

B = Φ / ΔA = Weber per square meter (Wb/m²)

Alternative Expressions

The SI unit of magnetic flux density can also be represented in terms of other fundamental quantities:

• 1 tesla (T) = 1 Weber per square meter (Wb/m²)
• It can also be expressed as newton per ampere-meter (N/A·m), relating it to the force experienced by a current-carrying conductor in a magnetic field.
