So, I want to build a solenoid. I have been looking around and have not found an equation to use for multi-layer solenoids. I have used the equation B=μnI
μ=k(μo) k=200 (μo) = 4(pi)*10^-7
n = N/L
N=number of turns (86 a row 3 rows)
L = Length of core (8in) = .203m
I =1000
My problem starts with current. I'm using a transformer to first change my power into ac and second to bump it up to 120v. I have .12 ohms resistance in my coil. So with doing the math I came up with 1000 amps. Is this the correct way of doing it?
So if I continue I have
μ = 200*(4(pi)*10^-7) = 2.513*10^-4 t/amp m
n = 86/.203 = 423.645 turns/m
I=1000a (from above)
so if I put it all together I get
B = 2.513*10^-4 T/amp m *1000 amp * 423.645 T/m
B = 157.721 T
Is this correct? I feel like it isn't for some reason.
Thank you,
