Answer:
I=800A
Explanation:
1) Important concepts
Magnetic field represented by B=0.1T, and is defined as"A field generated when an electric charge via electrons move through the space or in an electrical conductor."
I represent the current (variable os interest)
r represent the radius= 3.2/2 = 1.6mm = 0.0016m
2) Formula to use
For this case we can use the magnetic field due to a wire with current formula, given by:
[tex]B=\frac{\mu I}{2\pi r}[/tex]
[tex]\mu=4\pi x10^{-7} \frac{TA}{m}[/tex] is a constant
Solving for I from the last formula we got:
[tex]I=\frac{B(2\pi r)}{\mu}[/tex]
And replacing the values given we have:
[tex]I=\frac{0.1T(2\pix0.0016m)}{4\pi x10^{-7} \frac{TA}{m}}=800A[/tex]
So the current passing thorugh the wire would be 800 A.
