A toroid core has inner radius of \(0.24 \mathrm{~m}\) and outer radius of \(0.26 \mathrm{~m}\). A current of 10 A flows through the wire having 2500 turns around it. Find the magnetic field inside the core of the toroid.
- A \(\pi \times 10^{-2} \mathrm{~T}\)
- B \(2 \pi \times 10^{-2} \mathrm{~T}\)
- C \(2 \times 10^{-2} \mathrm{~T}\)
- D \(20 \times 10^{-2} \mathrm{~T}\)
Answer & Solution
Correct Answer
(C) \(2 \times 10^{-2} \mathrm{~T}\)
Step-by-step Solution
Detailed explanation
We have \(\mathrm{r}_{\mathrm{m}}=\frac{0.24+0.26}{2}=0.25 \mathrm{~m}\) As \(B=\mu_0 n I\)…
