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...

Solenoids are cylindrical coils of wire that create an internal magnetic field when carrying an electric current - see section 12.1 of the textbook. A solenoid 86.0 cm long has a radius of 3.00 cm and a winding of 1900 turns; it carries a current of 3.60 A. (a) Calculate the magnitude of the magnetic field inside the solenoid in mT. (b) Calculate the magnetic field outside the solenoid in T. (We can treat this as an ideal solenoid, since...

Problem 5: A 5 cm long wire is in a uniform magnetic field of 4T, so that current in the wire is perpendicular to the magnetic field. The wire is connected to a 10 ohm resistor in series, so that the resistance of the wire is negligible. The wire and resister are then connected in series to a charged 1500mF capacitor at 50 kV. A: What is the current through the wire as function of time, with t-0 being when...
