Question

What is the SI unit for flux density?

Answer 1

The SI unit for flux density is the **tesla (T)**. Flux density measures the amount of flux passing through a unit area. In the context of magnetic flux density, the tesla quantifies the strength of the magnetic field.

1 tesla is defined as 1 weber per square meter (1 T = 1 Wb/m²).

Answer 2

The SI unit for flux density depends on the type of flux being discussed. Here are the main types:

1. **Magnetic Flux Density**:
   - The SI unit is the **tesla** (symbol: T).
   - Magnetic flux density represents the strength of the magnetic field. One tesla is equal to one weber per square meter (1 T = 1 Wb/m²).

2. **Electric Flux Density**:
   - The SI unit is the **coulomb per square meter** (symbol: C/m²), also known as the electric displacement field, denoted by **D**.
   - This measures the amount of electric flux passing through a unit area in a material.

For both types of flux density, the units directly reflect the physical quantities involved:
- **Magnetic flux density** is related to the magnetic field strength and is measured in tesla.
- **Electric flux density** is related to the electric field and is measured in coulombs per square meter.
