Given Information:
Current = I = 61 A
Magnetic field = B = 1.30x10⁻⁴
Required Information:
Radius of wire = r = ?
Answer:
r = 0.093 meters
Step-by-step explanation:
Biot-Savart Law is given by
B = μ₀I/2πr
Where μ₀ is the permeability of free space and it is basically a measure of resistance in the formation of magnetic field.
I is the current flowing through the wire and B is the magnitude of the magnetic field produced.
Re-arranging the above equation to find out the radius of the loop
r = μ₀I/2πB
r = 4πx10⁻⁷*61/2π*1.30x10⁻⁴
r = 0.093 m
Hence, the radius of the loop wire is 0.093 meters.
