A straight section of the wire is 0.750 m long and lies along the y axis within a uniform magnetic field, = 1.90 T. If the current is in the positive y direction, what is the magnetic force on the section of wire? Magnitude DirectionThe earth's magnetic field is about 45 micro Tesla (μT) and points approximately due north. What is the force exerted by the field on a particle with a charge of 3.0 μC that is moving due west at a speed of 250 m/s? What is the direction of the force on the particle (i.e. north, south, east, west, up or down)?
