Magnetic force on current carrying wire

[superslow991]

Homework Statement

A wire along the z-axis carries a current of 6.8 A in the +z direction. Find the magnitude and direction of the force exerted on a 6.1-cm long length of the wire by a uniform magnetic field with magnitude 0.36 T in the -x direction.

Homework Equations

F=I(LxB)

The Attempt at a Solution

Now i already know the answer but i am confused as to what the direction the Force, field, and length are. I know this equation is dealing with cross product but if someone could explain to me in detail the direction of the Force (F), the field (B), and the length (L).

What do you think the directions are, and why, and what questions/doubts do you have about them? Then we can verify/correct your answers, and address your specific questions about them.

Thanks

What do you think the directions are, and why, and what questions/doubts do you have about them? Then we can verify/correct your answers, and address your specific questions about them.

So if I am reading right the direction of the Force is perpendicular to both the length and the magnetic field.
The length is in direction of the current in the wire
The field is?

Correct.

The length is in direction of the current in the wire

Correct.

The field is?

Perpendicular to both the length and the force.

Correct.

Perpendicular to both the length and the force.

Thanks a lot

Looks to me like they tell you the direction of the field.
(and the direction of the current)
