Sampaloc, Manila Philippines: Ronnie Belarmino Villamor & HR Publishing, pp.28-29 Magnetic Field of Solenoid When a coil has so many N loops, it is considered as a solenoid. Its magnetic field can be calculated using: B B = - HONI V4r2 + L The equation above is the general equation of Coil of wire a solenoid, if r > > L, we get (for N loop of coil) B = 2r Most solenoid has r
