(Take $μ_0 = 4 π × 10^{-7} T\, m\, A^{-1}$)

Options:

$3.2 π × 10^{-4}T\, m\, A^{-1}$

$3.2 × 10^{-4}T\, m\, A^{-1}$

$3.2 π × 10^{-5}T\, m\, A^{-1}$

$3.2 π × 10^{-7}T\, m\, A^{-1}$

Correct Answer:

$3.2 π × 10^{-4}T\, m\, A^{-1}$

Explanation:

The correct answer is Option (1) → $3.2 π × 10^{-4}T\, m\, A^{-1}$
