Magnet Force on a Current-Carrying Conductor

5. A present I sama dengan 15 A is described along the positive x-axis and perpendicular to a magnetic field. A magnetic force per unit period of 0. doze N/m acts on the conductor in the negative y-direction. Determine the value and way of the magnet field in the area through which the existing passes.

6. In Number 1, assume that in each case the speed vector proven is replaced with a cable carrying a current in the direction of the velocity vector. For every case, locate the way of the permanent magnetic force acting on the line.

7. In Figure two, assume that every time the velocity vector shown is usually replaced with a wire carrying a current in the direction of the velocity vector. For each case, find the direction from the magnetic discipline that will create the permanent magnet force proven.

8. A wire posesses current of 10. 0 A within a direction which makes an viewpoint of 31. 0 together with the direction of the magnetic field of power 0. three hundred T. Find the permanent magnetic force over a 5. 00-m length of the cable.

9. A wire 2 . 80 m in length carries a current of 5. 00 A in a region in which a uniform magnet field includes a magnitude of 0. 390 T. Compute the magnitude of the permanent magnet force on the wire, if, perhaps the angle between the magnet field and the current can be (a) 62. 0, (b) 90. 0, (c) 120.

12. A wasserstoffion (positiv) (fachsprachlich) moving readily in a circular path verticle with respect to a regular magnetic field takes 1 ) 00μs to complete one revolution. Identify the size of the permanent magnet field.

Section 19. 8Magnetic Force between Two Parallel Conductors

11. Two seite an seite wires will be 10. 0 cm a part, and each includes a current of 10. zero A. (a) If the currents are in the same path, find the force every unit length exerted on one of the wire connections by the other. Are the wiring attracted to or perhaps repelled by each other? (b) Repeat the problem with the power in opposite directions.
