Question

the diagram provided shows a straight wire carrying a current between the poles (north and south) of a permanent magnet. in what direction is the magnetic force experienced by the wire?
no magnetic force is exerted on the wire.
down
left
up
right

Explanation:

Step1: Apply Fleming's left - hand rule

Hold the left - hand such that the fore - finger points in the direction of the magnetic field (from N to S, i.e., upwards in this case), the middle finger points in the direction of the current (into the page as represented by the cross - symbol).

Step2: Determine the direction of the force

The thumb will then point in the direction of the magnetic force on the wire. According to the left - hand rule, the force is to the left.

Answer:

left
