A solenoid of length 0.5 m has a radius of 1 cm and is made up of 1000 turns. It carries a current of 10 A . What is the magnitude of the magnetic field inside the solenoid ?

  1. A \(2.51 \times 10^{-2} T\)
  2. B \(1.71 \times 10^{-2} T\)
  3. C \(6.28 \times 10^{-3} T\)
  4. D \(7.23 \times 10^{-3} T\)
Verified Solution

Answer & Solution

Correct Answer

(A) \(2.51 \times 10^{-2} T\)

Step-by-step Solution

Detailed explanation

A
\(\begin{array}{l} B =\mu_0 n I =\mu_0 \frac{N}{l} I \\ B =4 \pi \times 10^{-7} \times \frac{1000}{0.5} \times 10 \\ B=2.51 \times 10^{-2} T\end{array}\)
