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 is a fundamental concept in electromagnetism that quantifies the total magnetic field passing through a given area.
The calculator uses the magnetic flux formula:
Where:
Explanation: The formula shows that magnetic flux is directly proportional to magnetomotive force and inversely proportional to reluctance of the magnetic circuit.
Details: Accurate magnetic flux calculation is crucial for designing electromagnetic devices such as transformers, motors, generators, and magnetic sensors. It helps in understanding the efficiency and performance of magnetic circuits.
Tips: Enter magnetomotive force in Ampere-Turn and reluctance in Ampere-Turn per Weber. All values must be valid positive numbers.
Q1: What is magnetomotive force?
A: Magnetomotive force (MMF) is defined as the work done in moving a unit magnetic pole once around the magnetic circuit. It is analogous to electromotive force in electrical circuits.
Q2: What is reluctance in magnetic circuits?
A: The reluctance of a magnetic material is its ability to oppose the flow of magnetic flux. The magnetic flux created by the field windings follows the path of least magnetic reluctance.
Q3: What are typical units for magnetic flux?
A: Magnetic flux is measured in Weber (Wb) in the SI system. One Weber equals one volt-second.
Q4: How does material affect magnetic flux?
A: Different materials have different magnetic properties. Ferromagnetic materials have low reluctance and allow more flux, while non-magnetic materials have high reluctance.
Q5: What is the relationship between flux density and magnetic flux?
A: Flux density (B) is magnetic flux per unit area (B = Φ/A). It is measured in Tesla (T), where 1 T = 1 Wb/m².
