Answer:
The length of the wire is 579 m
Explanation:
Given;
current on the wire, I = 11.3-mA
magnetic field of the wire, B = (16.2i + 2.4 ĵ) T
Magnitude of force experience by the wire, F = 15.7 N
Magnitude of force experience by current carrying wire at a given a magnetic field strength is calculated as;
F = BILsinθ
Where;
B is magnitude of magnetic field
F is the force on the wire
L is length of the wire
θ is direction of the magnetic field
Length of the wire is calculated as;
Therefore, the length of the wire is 579 m
