    3 The magnetic field inside a toroidal solenoid is not uniform as for the long, straight solenoid. Over the cross-sectional area of the toroid the magnetic field is stronger near the inner HoNI radius of the torus and somewhat weaker near the outer radius according to B(r) 2Tr So we cannot technically use the simple expression P2 = BAfor the flux through one turn of wire. Nevertheless, the textbook uses an approximate constant value for an equivalent uniform magnetic field...

  • To leam about self-inductance from the example of a long solenoid.

    Learning Goal:To leam about self-inductance from the example of a long solenoid.To explain self-inductance, it is helpful to consider the specific example of a long solervid, as shown in the figure. This solenoid has only one winding, and so the EMF induced by its changing current appoars across the solenoid itsel. This contrasts with mutual inductance, where this voltege appears across a second coil wound on the same cylincter as the lirst.Part ASuppose that the current in the solenoid is...
