Electrical Engineering XYZ MCQ on Magnetic Flux Density is Scalar or Vector Quantity
Magnetic Flux Density is Scalar or Vector Quantity:
- Scalar quantity
- Vector quantity
- Phasor
- None of these
Correct answer: 2. Vector quantity
The correct answer to this Electrical Engineering XYZ MCQ is Vector. Let’s explain how
Explanation:
- Scalar: A scalar quantity has only magnitude and no direction. Examples include temperature, mass, and distance. Magnetic flux density is not a scalar because it has both magnitude and direction.
- Vector: A vector quantity has both magnitude and direction. Magnetic flux density (often denoted by the symbol B) is a vector quantity. It describes the strength and direction of a magnetic field at a specific point in space.
- Phasor: A phasor is a complex number representation of a sinusoidal waveform that simplifies the analysis of sinusoidal signals in the context of electrical engineering. Magnetic flux density is not represented as a phasor in its usual context; it’s typically represented as a vector.
- None of these: While magnetic flux density has characteristics of a vector, it is not accurately described as a phasor or a scalar.
In summary, magnetic flux density is a vector quantity, making option 2 the correct answer.
