Download Solution PDFThe correct answer is option 3):(1 wb = 108 lines of force)
Concept:
- The magnetic flux through a surface is the surface integral of the normal component of the magnetic field B over that surface. It is usually denoted Φ or ΦB.
- Magnetic flux is no. of the magnetic lines of force present per unit surface. Magnetic flux is often also called magnetic flux density. or even magnetic field line density.
- Weber (Wb) is the SI unit of magnetic flux, which is named after Wilhelm Eduard Weber, a German physicist.
- 1 wb = 108 lines of force
- Dimension: Wb = V⋅s = N⋅m⋅A−1 = kg⋅A−1⋅s−2⋅m2 = T⋅m2, where A stands for ampere, T for tesla, V for volt, and N for newton.
