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...
A toroidal solenoid with N turns of wire, has inner radius a, outer radius b, and a rectangular cross section of height h. Make a diagram of the toroid and its cross section and show that the self-inductance of this solenoid is given by L = [µ0N^2h/( 2π )]*ln(b/a).

Using the magnetic field and self-inductance of a long cylindrical solenoid derived in class, show that the magnetic field energy density inside the solenoid is given by uB = B^2/2µ0 . This result, even though you obtained it for a particular case, is general and it represents the energy density of the magnetic field in vacuum. In fact, it is completely analogous to uE = ε0E^2/2, the energy density of the electric field in vacuum.
The magnetic field inside a solenoid of circular cross section is given by B⃗ =btk^, where b = 3.0 T/ms . At time t = 0.32 μs , a proton is inside the solenoid at x = 5.6 cm , y= z=0 , and is moving with velocity v⃗ = 5.0 j^Mm/s . Part A Find the electromagnetic force on the proton. Express your answers using two significant figures separated by commas.
(a) Use the Ampere's law to show that the strength of the magnetic field inside an ideal cylindrical solenoid (a coil) is given off by B = µ(0)ni where n is the revolution density (the number of revolutions per unit length of the solenoid) and i is the current through the solenoid. (3p) The current in the solenoid increases at a constant rate to a constant value I in a certain time t. (b) Draw a figure across the cross...

6.1 Introduction—The design of a successful hot box appa- ratus is influenced by many factors. Before beginning the design of an apparatus meeting this standard, the designer shall review the discussion on the limitations and accuracy, Section 13, discussions of the energy flows in a hot box, Annex A2, the metering box wall loss flow, Annex A3, and flanking loss, Annex...
