B is the magnetic field inside the solenoid, in teslas. The direction of the field is parallel to the axis of the solenoid. There is no field outside the solenoid. μo is the permeability constant (1.26x10-6 H/m) i is the current in the wire, in amperes. n is the number of turns of wire per unit length of the solenoid, in 1/meters. |
