Hello guys(adsbygoogle = window.adsbygoogle || []).push({});

I have the following problem :

At a certain location, Earth has a magnetic field of 8.4 X 10^-5 T pointing 40 degree below the horizontal in a north-south plane. A 14.1m long straight wire carries a(n) 7 A current.

If the current is directed horizontally toward the east, what is the magnitude of the magnetic force on the wire?

I used the formula for the F = BIL sin Ө

so I get (8.4 X 10^-5 T)(7A)(14.1m) sin (40) = 0.0061775842N

for the magnetic force, but this is not the correct answer

Can anyone perhaps help me spot what am I doing wrong?
