- Determine the magnetic field in point P due to the conductor in the figure which carries a constant electrical current i. i ӨA solenoid of length 2.30 m and radius 2.00 cm carries a current of 0.130 A. Determine the magnitude of the magnetic field inside if the solenoid consists of 2400 turns of wire. TA conductor consists of a circular loop of radius R = 16.0 cm and two long, straight sections as shown in the figure below. The wire lies in the plane of the page and carries a current I = 1.2 A. Find the magnitude of the magnetic field (in μT) at the center of the loop. Round your answer to 2 decimal places.
- In the figure, point P2 is at perpendicular distance R = 26.9 cm from one end of straight wire of length L= 11.1 cm carrying current i = 0.977 A. (Note that the wire is not long.) What is the magnitude of the magnetic field at P2? P R R L. Number i UnitsIn the figure, four long straight wires are perpendicular to the page, and their cross sections form a square of edge length a 17.5 cm. Each wire carries 7.50 A, and the currents are out of the page in wires 1 and 4 and into the page in wires 2 and 3. In unit-vector notation, what is the net magnetic force per meter of wire length on wire 4? Number i ! Units N/mA thin 1.65 m long copper rod in a uniform horizontal magnetic field has a mass of 58.0 g. When the rod carries a current of 0.286 A directed perpendicular to the magnetic field, it floats in the magnetic field. What is the field strength of the magnetic field? Answer in units of T.
- Select the correct expression for the magnitude of electromotive force (e.m.f) of a straight conductor of length I moving with the velocity v perpendicular to a magnetic field B. Select one: a. € = Bu/I b. € = VBul C. E = Bul d. e = Bul?The magnitude of the magnetic field 70.0 cm from a long, thin, straight wire is 8.0µT. What is the current through the long wire? AS long, straight wire allows 3.5 A through it. What is the magnitude of the magnetic field 25 cm from the wire?
- So theres 2 long straight current-carrying wires are lined up parallel to one another at a distance ?d. Currents of 4 A and 2 A flow through the wires, both in the same direction generating the field of 9.2x10-6 T at a midpoint between them. Calculate the distance between the wires. Give your answer in SI units. Use ?0=4?×10−7μ0=4π×10−7 Hm-1.Four long, parallel conductors carry equal currents of I = 8.00 A. The figure shows a cross-sectional view of the conductors. The direction of currents is into the page for wires A and B and out of the page for wires C and D. Calculate the magnitude of the resulting magnetic field (in μT) at point P, located at the center of the square of edge length 0.400 m. Round your answer to 2 decimal places.
