INTERNAL MAGNETIC FIELD
B-Field Strength ($B$)0.0 mT
Turn Density ($n=N/L$)100 /m
■ Ampere's Law Derivation:
Using an Amperian rectangular loop inside an ideal solenoid, the internal magnetic field is uniform and horizontal, while the exterior field is weak (~0).
■ Central B-Field:
$B = \mu_0 n I$
$B = \mu_0 \left(\frac{N}{L}\right) I$
Where $\mu_0 = 4\pi \times 10^{-7}$ T·m/A.
Notice that $B$ is independent of the solenoid's radius. It depends exclusively on turn density ($n$) and current ($I$).
