A. Down
Step-by-step explanation:
- To determine the direction of the force on the wire, we can use the right-hand rule for the cross product of two vectors. The force on the wire is given by:
- F = I * L x B
where I is the current, L is the length of the wire, and B is the magnetic field.
If we point our right-hand thumb in the direction of the current (to the right), and our fingers in the direction of the magnetic field (away from us), then our palm will point in the direction of the force.
- So, using the right-hand rule, we can see that the force on the wire will be directed downward. Therefore, the correct answer is A. Down.
