Physics magnet conceptual question

Homework Statement

The figure shows a wire that is connected to a power supply and suspended between the poles of a magnet. When the switch is closed, the wire deflects in the direction shown.

Which of the dashed boxes A–D represents the position of the north magnetic pole?

Homework Equations

Right hand rule?

The Attempt at a Solution

When I attempt the right hand rule and line my thumb up with the wire I don't see how the wire could deflect downward. Shouldn't it be right or left deflection?

I must be missing something

bump... help me understand this

anyone? I don't know how to go about this... and yes I've read the chapter

It's more accurate if you use your

index finger (current)
thumb (force)
middle finger (magnetic field).

You, however, are lacking the picture or a more detailed description of the problem. This is probably why no one has responded.

The correct answer is D. The wire is deflecting downwards because the north magnetic pole is located at the top of the magnet, which is represented by box D. The right hand rule can be applied to determine the direction of the deflection, but it is important to also consider the orientation of the magnet. In this case, the north pole is facing downwards towards the wire, which causes the wire to deflect downwards. This is due to the interaction between the magnetic field of the wire and the magnetic field of the magnet.
