螺线管磁场计算器

我们所说的螺线管是指一个紧密间隔的绕组，其长度明显大于直径的大小。当螺线管被一定强度的电流通过时，它会产生磁场。

By solenoid we mean a closely spaced winding of turns whose length is significantly greater than the size of the diameter. When a solenoid is crossed by an electric current of a certain intensity, it generates a magnetic field.

由绕在空气中的线圈组成的螺线管的磁场强度 B（即没有铁磁芯）可以使用以下公式计算：

where:
μ₀ = 4Π x 10^-7 H/m is the magnetic constant (vacuum permeability)
N is the number of turns
I is the current intensity, in Ampere
L is the solenoid length, in meter
B is expressed in Tesla (T)

Example 1

N = 500
I = 5 A
L = 10 cm
B = 0.03142 T

Example 2

N = 1000
I = 10 A
L = 15 cm
B = 0.08378 T
