- A portion of a long, cylindrical coaxial cable is shown in the figure below. An electrical current I = 3.0 amps flows down the center conductor, and this same current is returned in the outer conductor. Assume the current is distributed uniformly over the cross sections of the two parts of the cable. The values of the radii in the figure are r1 = 1.5 mm, r2 = 4.0 mm, and r3 = 7.0 mm. Using Ampere’s Law, find the magnitude of the magnetic field at the following distances from the center of the inner wire: a. 1.0 mm. b. 3.0 mm. c. 5.5 mm. d. 9.0 mm.arrow_forwardA wire consists of a vertical wire whose ends are connected to a circular wire. Suppose that the vertical wire has end points at rд = −2 cos 60° î+ Rsin 60° ĵ and rß = −R cos 60° î - R sin 60° ĵ, with the positive current I flowing from point A to point B. On the other hand, the circular wire has a radius R centered at the origin and passes through points A, B, and C, with the position rc = Rî. If a positive current I flows along the wire, passing through the points A, B, C, and back to A, use Biot-Savart law to find the resulting magnetic field at point D, where rp = zk.

One wire is in the x-z plane and it carries a current of 1₁ = 42 A. This wire is a distance of r₁ = 7 m from the z axis. The other wire is in the y-z plane and it carries a current of 12 = 23 A. This wire is a distance of r2 = 8 m from the z axis. What is the magnitude of the net magnetic field at the origin in nano Tesla? 1.0 nano Tesla = 109 Tesla.

The center conductor is surrounded by a rubber layer, which is surrounded by an outer conductor, which is surrounded by another rubber layer. In a particular application, the current in the inner conductor I 2 is 7.00 A out of the page and the current in the outer conductor I 1 is 5.00 A into the page. Assume that l = 1.20 mm. Determine the magnitude and direction (upward or downward of the page) of the magnetic field at point a. (Choose upward of the page as the positive y-direction and express the magnetic field by using the sign of the result, which must be in µT and without decimals. That means if you get a result of a 922 and the direction of the field is upward of the page, just type 922 or if you find the direction of the field as downward of the page, just tpe -922 in the answer box.

- 26 O In Fig. 29-54a, wire 1 consists of a circular arc and two radial lengths; it carries current = 0.50 A in the direction indicated. Wire 2, shown in cross section, is long, straight, and per- pendicular to the plane of the figure. Its distance from the center of the arc is equal to the radius R of the arc, and it carries a current iz that can be varied. The two currents set up a net magnetic field B at the center of the arc.

A tabletop model rail gun (as shown) consists of two long, parallel, horizontal rails ℓ = 3.50 cm apart, bridged by a bar of mass m = 3.00 g that is free to slide without friction. The rails and bar have low electric resistance, and the current is limited to a constant I = 24.0 A by a power supply that is far to the left of the figure, so it has no magnetic effect on the bar. As shown the bar at rest at the midpoint of the rails at the moment the current is established. We wish to find the speed with which the bar leaves the rails after being released from the midpoint of the rails.
