You are watching: What current will you need to produce the necessary field?
As a new electric technician, you are creating a huge solenoid to produce a uniform 0.1 T magnetic field close to the facility of the solenoid
As a new electrical technician, you are developing a huge solenoid to develop a unicreate 0.1 T magnetic area near the center of the solenoid. You have enough wire for 4000 circular turns. This solenoid must be 1.0 m long and also 3.0 cm in diameter. What existing will you must develop the essential field?
B = μI (N/L)
B = magnetic field toughness = 0.1T
μ = 4Π * 10⁻⁷ T.A/m
I = present passing through the solenoid = ?
N = variety of turns = 4000
L = size of the solenoid = 1m
I = B / μ (N/L)
I = 0.1 / <4Π*10⁻⁷ * (4000/1)>
I = 0.1 / 5.03*10⁻³
I = 19.89A
Magnetic area stamina, B = 0.1 T
Number of feasible turns, N = 4000
Length of solenoid, L = 1 m
Diameter of solenoid = 3 cm = 0.03 m
Radius of solenoid, r = 0.03/2 = 0.015 m
Magnetic area strength, B, is offered as:
wbelow I = current
Making current, I, subject of formula, we have actually that:
The existing needed to develop the magnetic field is 1.6 mA
