MHT CET 2024 Physics question
A current of 5A flows through a toroid having a core of mean radius 20 cm. If 4000 turns of the conduction wire are wound on the core, then the magnetic field inside the core of the toroid is [permeability of free space = SI units]
Answer: (D)
Solution
For a toroid the field inside the core is with , where is the mean radius. turns per metre. So \dfrac{4π×10^{-7}×4000×5}{2π×0.2}$ =
