Question

Figure shows a cross section of a long conducting coaxial cable with the
radii, a, b and c. The inner wire has a current density,
Jwire = Jo (1
O out of page.
The shell has current density,
Jshell =
O into the page.
= Jo
r
What is the magnitude of the magnetic field at the point P , for r = 2a, where a <r < b?
(Assume the region between the inner wire and the outer cylindrical shell is filled with air.)

Magnetic and electric field lines are in many ways similar, with few crucial differences. Which of the properties listed below does NOT apply to both fields? O All of these properties apply to both E and B field lines. The density of lines is proportional to the field strength in that area. Field lines never intersect. Tangent to the line at a point gives you the direction of the field as that point. O Field lines form closed loops.
A loop of wire is perpendicular to a magnetic field. The magnetic field strength as a function of timeis given by the top graph. Draw a graph of the current in the loop as a function of time. Let apositive current represent a current that comes out of the top of the loop and enters the bottom of theloop. There are no numbers for the vertical axis, but your graph should have the correct shape andproportions.

Connecting arc A wire with current i = 7.2 A is shown. Two semi- infinite straight sections, both tangent to the same circle, are connected by a circular arc that has a central angle and runs along the circumference of the circle. The arc and the two straight sections all lie in the same plane. If B = 0 at the circle's center, what is in rads?

Consider a long, horizontal Large Wire with current of 10 A running through it. We want to levitate a horizontal, thin, 0.50 m length of wire above it. If the thin wire has a mass of 10 grams, and a current of 300 mA, how far above the Large Wire will it hover (net force of zero) due to magnetic and gravitational forces? A. If the thin wire hovers above the Large Wire due to their magnetic fields, are their currents going the same direction, or opposite directions. Explain. B. Draw a diagram and label the directions of currents, and all other relevant quantities and vectors. C. Find the distance above the Large Wire the small thin wire will hover (net force of zero). D. Would your answers to parts A and C change if we wanted to find a distance below (rather than above) the Large Wire that the smaller thin wire could hover, due to their magnetic fields. Explain. Don't calculate any values but draw a new diagram and explain how this situation compares to the problem above.
