Faraday’s Law and Induced EMF
The figure displays a rectangular loop of wire with sides x and
y placed in a region where a uniform magnetic field ! exists. The
resistance of the loop is R. Initially the field is perpendicular
to the plane of the loop and is directed out of the page. The loop
can rotate about either the vertical or horizontal axis, passing
through the midpoints of the opposite sides, as shown.

In one of NASA's space tether experiments, a 20.0 km-long conducting wire was deployed by the space shuttle as it orbited at 7.86 x 103 m/s around Earth and across Earth's magnetic field lines. The resulting motional emf was used as a power source. If the component of Earth's magnetic field perpendicular to the tether was 1.65 x 10T, determine the maximum possible potential difference (in V) between the two ends of the tether. HINT

A transformer is constructed from a long wire carrying current I-ilocos() passes through a toroidal ferrite which has μ,-100, inner radius-a, outer radius-b, and depth (z dimension) - c. N turns of wire are wrapped tightly around the ferrite. The current creates a magnetic flux through the N-turn coil, which, in turn, induces a voltage, Vind, across the coil, as shown. a) Find an expression for the flux density, B, in the ferrite. b) Find an expression for the flux,...

1. Magnetic Field Generated by a Current in a Wire Under steady-state conditions, a magnetic field B has curlB in a region where there is no current. We study the steady-state magnetic field B due to a constant current in an infinitely long straight thin wire. The magnitude of the magnetic field at a point depends only on the distance from the wire and its direction is tangent to the circle around the wire and determined by the right-hand rule....

1. A copper wire is carrying 5.0 A of current. Given that the electric field between the ends of the cable has a value of 0.75 V/m. Answer the following questions: (50 points) . Find the current density in the wire. .Find the drift speed of the mobile charges. For this you will need the density of copper, D 8960 0.063 kg/mol. Assume each atom of iron contributes kg/m3 and the molar mass of copper, m with one electron. ....
