Answer:
The magnitude of the current flowing through the wire is 7 A.
Explanation:
Given that,
Radius of the circular loop, r = 4 mm = 0.004 m
Magnetic field at the centre of the loop, B = 1.1 mT
We need to find the magnitude of the current flowing through the wire. The magnetic field at the center of the loop is given by the formula as follows :
[tex]B=\dfrac{\mu_oI}{2r}\\\\I=\dfrac{2Br}{\mu_o}\\\\I=\dfrac{2\times 1.1\times 10^{-3}\times 0.004}{4\pi \times 10^{-7}}\\\\I=7\ A[/tex]
So, the magnitude of the current flowing through the wire is 7 A.
