Answer:
The magnitude of the magnetic field created is 5 x 10⁻⁷ T
Explanation:
Given;
magnitude of current, I = 10.0 A
distance of the magnetic field, r = 4.0m
Apply Biot-Savart Law to determine the magnitude of of the magnetic field created;
[tex]B = \frac{\mu_oI}{2 \pi r}[/tex]
where;
B is the magnitude of of the magnetic field
μ₀ is constant
I is current
r is the distance of the field
[tex]B = \frac{4 \pi*10^{-7} *10}{2 \pi*4} = 5*10^{-7} \ T[/tex]
Therefore, the magnitude of the magnetic field created is 5 x 10⁻⁷ T
