Magnetic force calculation

[kevinm829]

Homework Statement

A wire 48.3 cm long carries a 0.710 A current in the positive direction of an x-axis through a magnetic field with an x component of zero, a y component of 0.000410 T, and a z component of 0.00850 T. Find the (a) x, (b) y, and (c) z components of the magnetic force on the wire.

Relevant Equations

Force on a wire: F=i*(crossP(L,B))

I am getting a wrong answer for part b, however part a and c both are correct :
a. 0 N
b = -2.91E-3 N (WRONG)
c. 1.4E-4 N

I get the same answer as you. If this is a machine-graded problem, show your solution to whomever assigned it to you an ask about it. But before you do that, check the numbers again and make sure you copied everything correctly from the textbook.
