Answer:
The magnetic field inside a coil is 0.0119 T.
Step-by-step explanation:
Given that,
Number of turns = 228
Current = 0.952 A
Length = 2.29 cm
We need to calculate the magnetic field
Using formula of magnetic field

Where, B = magnetic field
l = length
I = current
N = number of turns
Put the value into the formula


Hence, The magnetic field inside a coil is 0.0119 T.
