Two long, straight wires are separated by 0.120 m. The wires carry currents of 12 A in opposite directions, as the drawing indicates. Find the magnitude of the net magnetic field at the points labeled (a) A and (b) B. 0.060 m B 0.030 m 0.120 m

A very long wire bears a current of 0.50 A. What is the magnitude of the magnetic field 0.35 meters from the wire? Recall that in the case of an infinitely long straight wire, that the magnetic field strength is: Họi B (1) 2ar О А. 2.9 х 10-3т В. 2.9 х 10-5 Т C. 2.9 × 10-7 T D. 2.9 x 10-9 T

A particle of mass 8.1 × 10-8 kg and charge +5.4 µC is traveling due east. It enters perpendicularly a magnetic field whose magnitude is 3.5 T. After entering the field, the particle completes one-half of a circle and exits the field traveling due west. How much time does the particle spend in the magnetic field? Number i Units

Two parallel wires, each carrying a current of 2.2 A in the same direction, are shown. Find the direction and magnitude of the net magnetic field at point A. Wire 1 2.2A 7.5 cm 7.5 cm B Wire 2 2.2A 75 cm 7.5 cm 7. 82 × 10¬0 T into page O7.82 × 10° T out of page

In the figure below, four long straight wires are perpendicular to the page, and their cross-sections form a square of edge length a = 10.5 cm. Each wire carries 8.00 A, and the currents are out of the page in wires 1 and 4 and into the page in wires 2 and 3. What is the magnitude and direction of the net magnetic force per meter of wire length on wire 4? magnitude      N/m direction      ° (counterclockwise from the positive x-axis) (please show units. It really helps me out)

Disregard the moving charge off to the right. The diagram above shows segments of two long straight wires, carrying currents I1 = 3.83 A and I2 = 4.68 A respectively. The distance between the wires is 3.55 cm. What is the force on a 7.43-cm segment of wire #2 due to the magnetic field from wire #1?  7.50E-06 N  6.00E-06 N  9.75E-06 N  1.35E-05 N

Disregard the charge off to the right. The diagram above shows segments of two long straight wires, carrying currents. This time, I1 = 9.42 A and I2 = 4.89 A; the separation between the wires is 7.88 cm. How far to the right of wire #1 will be total magnetic field due to both wires be equal to zero? 9.34 cm   5.19 cm  2.60 cm  6.23 cm
