What are the units of magnetic flux density?

Magnetic flux density is a measure of the strength of a magnetic field in a given area. The units used to express magnetic flux density are Webers per meter squared (Wb/m²). This unit indicates how much magnetic flux (measured in Webers) passes through a unit area (measured in square meters).

The concept of magnetic flux density is critical in electromagnetic theory, particularly when analyzing how magnetic fields interact with electric currents and materials. The unit Wb/m² can also be referred to as Tesla (T), which is the standard unit of magnetic flux density in the International System of Units (SI).

Understanding that magnetic flux density involves concepts of both magnetic flux and area is essential for grasping how magnetic fields behave in different contexts, such as in machinery or in the study of electromagnetic waves.
