Magnetic Flux Formula:
| From: | To: |
Magnetic flux (Φ) is the number of magnetic field lines passing through a surface (such as a loop of wire). It represents the total magnetic field that passes through a given area and is measured in Weber (Wb).
The calculator uses the magnetic flux formula:
Where:
Explanation: The magnetic flux through a surface is equal to the product of the magnetic flux density and the area of that surface, when the magnetic field is perpendicular to the surface.
Details: Magnetic flux calculation is crucial in electromagnetic theory, electrical engineering, and physics. It helps in understanding electromagnetic induction, transformer design, motor operation, and various electromagnetic phenomena.
Tips: Enter magnetic flux density in Tesla, area in square meters. Both values must be positive numbers greater than zero.
Q1: What is the unit of magnetic flux?
A: Magnetic flux is measured in Weber (Wb) in the SI system.
Q2: How does angle affect magnetic flux?
A: When the magnetic field is not perpendicular to the surface, the formula becomes Φ = B × A × cosθ, where θ is the angle between the magnetic field and the normal to the surface.
Q3: What is the relationship between magnetic flux and induced EMF?
A: According to Faraday's law, the induced electromotive force (EMF) in any closed circuit is equal to the negative of the time rate of change of the magnetic flux through the circuit.
Q4: Can magnetic flux be negative?
A: Yes, magnetic flux can be negative when the angle between the magnetic field and the surface normal is greater than 90 degrees, indicating the direction of the flux.
Q5: What is the difference between magnetic flux and magnetic flux density?
A: Magnetic flux density (B) is the amount of magnetic flux per unit area, while magnetic flux (Φ) is the total magnetic field passing through a given area.
