Definition of Magnetic Flux
Magnetic flux is defined as the total number of magnetic field lines passing through an area. It is represented by the symbol ΦB.
Mathematically, magnetic flux can be expressed as:
ΦB = B * A * cos(θ)
Where B is the magnetic field strength, A is the area, and θ is the angle between the surface normal and the magnetic field.
Explanation of Options
a) Voltage: Voltage is the difference in electric potential between two points. It is measured in volts (V) and is often represented by the symbol V. Voltage is not related to magnetic flux.
b) EMF: EMF stands for electromotive force. It is the voltage generated by a source such as a battery or generator. EMF is measured in volts (V) and is often represented by the symbol E. EMF is not related to magnetic flux.
c) Magnetic Flux: Magnetic flux is the correct answer to the question. It is the total number of magnetic field lines passing through an area and is represented by the symbol ΦB.
d) Magnetic Flux Density: Magnetic flux density is a measure of the strength of a magnetic field. It is represented by the symbol B and is measured in teslas (T). Magnetic flux density is related to magnetic flux, but it is not the correct answer to the question.
Conclusion
The correct answer to the question is magnetic flux. Magnetic flux is the total number of magnetic field lines passing through an area and is represented by the symbol ΦB.
