Question

The magnetic induction at a point 1cm from a thin, infinitely long, straight wire carrying a current is 100micro Tesla. What is the current in the conductor.

Answer 1

Answer:

this is the required answer.Hope it helps

Answer 2

Answer:

0.05A

Explanation:

Let the length of the wire is a = 1 cm = $10^{-2}$m.

B = 100∪TI(1+1)/4$\pi$a

=> $10^{-4}$ = $10^{-7}$×$\frac{2I}{10^{-2} }$

=> I = $\frac{10^{-4-2} }{2*10^{-7} }$ = $\frac{10^{-1} }{2}$

=> I = 0.05A

Hence, the current in the conductor is 0.05A
