Magnetic Flux Unit: Weber
Magnetic flux ($ \Phi_B $) represents the quantity of a magnetic field that passes through a specified area. The standard international (SI) unit used to measure magnetic flux is the Weber, symbolized as $ Wb $.
Analyzing Unit Options for Magnetic Flux
Let's review the provided options to determine the correct unit:
- Pascal ($ Pa $): This unit measures pressure or stress. It is not related to magnetic flux.
- Farad ($ F $): This is the SI unit for electrical capacitance, which measures the ability to store electric charge. It is not the unit for magnetic flux.
- Henry ($ H $): This is the SI unit for inductance, relating a change in current to the induced voltage. It is not the unit for magnetic flux.
- Weber ($ Wb $): This is the defined SI unit for magnetic flux. It is equivalent to one volt-second ($ V \cdot s $). This is the correct unit.
Therefore, the unit of magnetic flux is Weber.
