Answer:
magnetic field is 0.122 mT
Explanation:
Given data
length = 2.50 m
radius = 1.70 cm
current = 0.110 A
turns of wire = 2200
to find out
magnitude of the magnetic field
solution
we know the relation of current turn and length with magnetic field i.e
magnetic field = ( μ × turn × current ) / length
here μ is permeability
magnetic field = ( μ × turn × current ) / length
magnetic field = ( 4π × [tex]10^{-7}[/tex] × 2200 × 0.110) / 2.50
magnetic field = ( 4π × [tex]10^{-7}[/tex] × 2200 × 0.110) / 2.50
magnetic field = 0.000122
so magnetic field is 0.122 mT
