There is a uniform magnetic field present, given by B=0.0031+ 0.004] + 0.002k, where i, j, k are the unit vectors along the cartesian coordinate axes) in units of Tesla. Calculate the y-component of the magnetic force acting on a segment of wire of length L = 14.0 cm 1.43 10A-3 N Use the formula for the magnetic force on a straight wire carrying current in a uniform magnetic field. You can find the cross product by applying the right hand rule separately for each B component. © 1998-2014 by Florida State University.

only z componet of magnetic filed contributes to force in y -direction.
Fy = i*(L cross Bz)
= -Bz*i*L*sin(90)
= 0.002*1.4*0.14
= -3.92*10^-4 N j
