What is the direction of the resulting force on this current

[elitechic26]

Homework Statement

A vertical wire carries a current straight up in a region where the magnetic field vector points due north. What is the direction of the resulting force on this current?

The diagram shows a force arrow perpendicular to the B (magnetic field arrow). The magnetic field is pointing out of the page.

Homework Equations

RHR
Fingers - pt I
Palm - magnetic field
Thumb- direction of force

The Attempt at a Solution

When I place my thumb in the direction of the arrow marked "F", it goes to the left (west) but I am having trouble lining every component of the RHR up.
