The magnetic force on a straight wire .69 m long is 1.5 x 10^-3 N. The current in the wire is 16.9 A. What is the magnitude of the magnetic field that is perpendicular to the wire?

An electron is moving paralel to the Earth's surface at the equator in a direction 12 degrees south of east. Its velocity is 9.2 x 10^4 m/s and a magnetic force of 9.4 x 10^-18 N is exerted on the electron. If the magnetic field points south at this locat...
