Suppose a long, straight, current- carrying wire had a current from west to east. If it were immersed in a vertically upward magnetic field that was stronger on its west side than on its east side, what would be the initial motion of the wire if released from rest? Explain.
Answer to relevant QuestionsGiven two solenoids, one with 100 turns and the other with 200 turns. If both carry the same current, will the one with more turns necessarily produce a stronger magnetic field at its center? Explain. Determine the direction of the force due to the Earth’s magnetic field on an electron near the equator when the electron’s velocity is directed (a) Due south, (b) North-west, and (c) Upward. (a) What angle(s) does a particle’s velocity have to make with the magnetic field direction for the particle to be subjected to half the maximum possible magnetic force, Fmax? (b) Express the magnetic force on a charged ...In a mass spectrometer, a beam of protons enters a magnetic field. Some protons make exactly a one-quarter circular arc of radius 0.50 m. If the field is always perpendicular to the proton’s velocity, (a) What is the ...A nearly horizontal dc power line in the midlatitudes of North America carries a current of 1000 A directly eastward. If the Earth’s magnetic field at the location of the power line is northward with a magnitude of 5.0 x ...
