Answer:
The magnetic field strength due to current flowing in the wire is9.322 x 10⁻⁶ T.
Explanation:
Given;
electric current, I = 21.3 A
distance of the magnetic field from the wire, R = 45.7 cm = 0.457 m
The strength of the resulting magnetic field at the given distance is calculated as;
Where;
μ₀ is permeability of free space = 4π x 10⁻⁷ T.m/A
Therefore, the magnetic field strength due to current flowing in the wire is 9.322 x 10⁻⁶ T.
