Q#1 At a certain location, Earth has a magnetic field of 0.60? 10-4 T, pointing 75° below the horizontal in a north-south plane. A 10.1 m long straight wire carries a 10 A current. (a) If the current is directed horizontally toward the east, what are the magnitude and direction of the magnetic force on the wire? Magnitude N Select15° above the horizontal in the northward direction 15° below the horizontal in the southward direction 75° below the horizontal in the southward direction horizontal and directed due east horizontal and directed due west 75° above the horizontal in the northward direction Direction (b) What are the magnitude and direction of the force if the current is directed vertically upward? Magnitude N Select-- 15° above the horizontal in the northward direction horizontal and directed due west 75° above the horizontal in the northward direction 75° below the horizontal in the southward direction horizontal and directed due east 15° below the horizontal in the southward direction DirectionExplanation / Answer
a)
Magnetic field due to current carrying wire is
F = BIL sin(theta)
F = 0.60 x 10^-4 T x 10 A x 10.1 m x sin(75)
F = 0.00585 N
F = 5.85 x 10^-3 N
direction is 15 degree above the horizontal in the northward direction.
b)
The magnitude of the force acting in the current is directed vertically upward
F = BIL sin(theta)
F = 0.60 x 10^-4 T x 10 A x 10.1 m x sin(75 + 90)
F = 0.60 x 10^-4 T x 10 A x 10.1 m x sin(165)
F = 0.001568 N
F = 1.568 x 10^-3 N
