Magnetic field stored in an inductor?

  1. Oct 1, 2005 #1
    Does anyone know how a magnetic field stored in an inductor (like a solenoid) can be used to light a globe (when connected via a circuit)?

    I assume there must be a changing magnetic flux caused by a change in magnetic field in the inductor so as to induce an electric field causing a potential difference between the ends of the inductor. But I do not know how a change in the magnetic field can be established. Does the magnetic field automatically change just like how a capcitor automatically discharges when connected? If so I do not know the why behind it.
