A wire carries current out of a page. The wire has a radius of 17mm. The current is spread uniformly over the cross-section of the wire and has a constant current of 23.2A Find the magnitude of the magnetic field 6mm from the center of the wire
Three parallel wires carry current into and out of the page. Wire 1 carries 4.00 A of current into the page at the origin. Wire 2 carries 5.00 A of current out of the page 1/2 d to the right of the origin along the +x axis. Wire 3 carries 8.00 A of current into the page at a point directly below wire 2, located a distance d away from the origin. (a) What is the direction of the net...
A long horizontal wire carries a current I=5A out of the page, as shown in the image below. Calculate the magnitude and direction of the magnetic field at point A, 20 cm to the right of the wire. 20cm A long horizontal IÓ A
Problem 20.71 A long, straight wire carries a current of 10.0 A, as shown in the figure 5.00 cm A ←-7.00 cm 10.0A Part A Use the law of Blot and Savart to find the direction of the magnetic field at point P due to the 2.20 mm segment A ANSWER The field is directed into the page. The field is directed out of the page. The field is directed to the right. The field is directed to the left....
A 2mm long wire carries a current of 0.5A directed out of the page. The magnetic field due to this bit of wire at a point P which is 3 meters to the right of and 3 meters lower than the wire (see the figure below) is a)5.56 x 10^-12 T pointing upwards 45 degrees to the right b)5.56 x 10^-12 T pointing downwards 45 degrees to the left c)3.93 x 10^-12 T pointing upwards 60 degrees to the right...
A straight wire carries a 10.0-A current. ABCD is a rectangle with point D in the middle of a 1.10-mm segment of the wire and point C in the wire. Find the magnitude and direction of the magnetic field due to this segment at (a) point A; (b) point B; (c) point C.
A straight vertical wire carries a current of 1.0 A into the page in a region where the magnetic field strength is 0.60 T. What is the magnitude and direction of the magnetic force on a 1.0 cm section of this wire if the magnetic field direction is toward the east?
A 2.9 mm -diameter copper wire carries a 40 A current (uniform across its cross section). a)Determine the magnetic field at the surface of the wire. b)Determine the magnetic field inside the wire, 0.50 mm below the surface. c)Determine the magnetic field outside the wire 2.5 mm from the surface.
4.A coaxial cable has an inner core of copper wire with a 3 mm diameter with a current density of 1.768E4 A/m2. The image shows a cross-sectional area of the wire. The current in the core is flowing out of the page. The core is surrounded by a thin sheath of insulating material, 1mm thick. Surrounding this is a thin cylindrical shell of copper wire 1mm thick, that carries the returning current back into the page. The copper shell is...
