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? up left no magnetic force is exerted on the wire. right down

Explanation:

Step1: Apply Fleming's left - hand rule

The middle finger represents the direction of the current (into the page as shown by the cross - symbol), the index finger represents the direction of the magnetic field (from N to S, i.e., from right to left), and the thumb represents the direction of the force.

Step2: Determine the force direction

When we position our left - hand as per Fleming's left - hand rule with the middle finger into the page and index finger from right to left, the thumb points downwards.

Answer:

down
