The magnetic field of a long thin solenoid is approximately zero outside the solenoid and a uniform Bsol inside the solenoid. A square conducting frame is located as shown. The large frame is located entirely outside the solenoid while the small frame is located entirely inside the solenoid. The frame and solenoid are oriented so their axis coincide. What is the magnetic flux through the square frame?
A. Bsol times the area of the frame for the top case and Bsol times the cross sectional area of the solenoid for the bottom case.
B. Bsol times the area of the frame for both cases.
C. Bsol times the cross sectional area of the solenoid for the top case and Bsol times the area of the frame for the bottom case.
D. Zero for the top case and Bsol times the area of the frame for the bottom case.
E. Bsol times the area of the frame for the top case and zero for the bottom case.
F. Bsol times the cross sectional area of the solenoid for both cases.

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...

The magnetic field inside a toroidal solenoid is discussed in Example 28.11 of the text book. There the thickness of the solenoid and variation of the magnetic field across the cross section were ignored. Let's include these effects into consideration. The solenoid in the figure has a rectangular cross section. It has N uniformly spaced turns, with air inside. The magnetic field at a point inside the toroid was derived in Example 28.11. Do not assume the field to be...

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.

Problem 5: The magnetic field strength in a long superconducting solenoid buried underground in Switzerland is 15:0 T. The cross sectional area of the solenoid is 3.0x10^-4 m^2 ; and its length is approximately 40 km. If a loss of cooling allows the superconducting wires to suddenly become normal, so that B drops to zero, how much energy will be released as heat?

Calculate the magnetic field inside and outside an infinitely long solenoid of radius R that carries a current I and has N windings per meter (pretend that the windings are circular). Make sure that you use symmetry to show that some components of the magnetic field are zero, and indicate the symmetry operations you use to do so. Also makes sure that you make drawings of the 3 Amperian loops that you use and indicate which part of the integrals...

An ideal solenoid generates a uniform magnetic field inside the solenoid. Here we place two long ideal solenoids as shown (with radii 40 mm and 20 mm, respectively). The current carried by the outer solenoid It is three times as large as the current carried by the inner solenoid I2. In order to make the magnetic field inside the inner solenoid zero, what should be the ratio of the number of turns per unit length for the...
