Calculate the MMF when the magnetic flux is 5Wb and the reluctance is ...
We know that:
F=ϕS
Substituting the given values from the question, we get MMF= 15At.
F=ϕS
Substituting the given values from the question, we get MMF= 15At.

Calculate the MMF when the magnetic flux is 5Wb and the reluctance is ...
The given question is asking to calculate the MMF (magnetomotive force) when the magnetic flux is 5 Wb (webers) and the reluctance is 3 A/Wb (ampere-turns per weber).
To calculate the MMF, we can use the formula:
MMF = Magnetic Flux * Reluctance
Given:
Magnetic Flux = 5 Wb
Reluctance = 3 A/Wb
Let's plug in the values into the formula:
MMF = 5 Wb * 3 A/Wb
Simplifying the expression:
MMF = 15 A
So, the correct answer is option 'D', 15 At (ampere-turns).
Explanation:
- MMF (magnetomotive force): It is the force that produces magnetic flux. It is analogous to electromotive force (EMF) in an electrical circuit.
- Magnetic Flux: It is a measure of the total magnetic field passing through a given area. It is represented by the symbol Φ and measured in webers (Wb).
- Reluctance: It is the opposition offered by a magnetic circuit to the establishment of magnetic flux. It is analogous to resistance in an electrical circuit. It is represented by the symbol R and measured in A/Wb (ampere-turns per weber).
- The formula to calculate MMF is MMF = Magnetic Flux * Reluctance.
- In this case, the given magnetic flux is 5 Wb and the reluctance is 3 A/Wb.
- Plugging in these values into the formula, we get MMF = 5 Wb * 3 A/Wb = 15 A.
- Therefore, the correct answer is option 'D', 15 At (ampere-turns).
