A wire runs from point “a" (x = 2, y = 3, z = - 4) to point “b" (x = 10, y = 15, z = 12) carrying a current of 10 amps in the direction from point "a" to point "b". If the wire is immersed in a magnetic field of B = 2î - ĵ + 4k (µT) then what is the force exerted on it by the magnetic field? (in µN) a. 640î + 320k b. - 640î + 320k c. - 640î - 320k d. 640î - 320k e. I haven't got a clue – fail me !!!
