Answer:
The magnetic field in the center of the solenoid is .
Explanation:
Given that,
Length of solenoid = 0.425 m
Number of turns N = 950
Current I = 2.75 A
The magnetic field in the center of the solenoid is the product of the current , number of turns per unit length and permeability.
In mathematical form,
Where,
N = number of turns
L = length
I = current
Now, The magnetic field
Put the value into the formula
Hence, The magnetic field in the center of the solenoid is .
