The discussion centers on determining the direction of the magnetic force acting on a long wire with current flowing from west to east and a magnetic field directed into the page. Using Fleming's left-hand rule, the current (middle finger) is aligned from left to right, and the magnetic field (index finger) points into the page. The confusion arises when applying the rule, as the thumb, representing the force, appears to point upwards, while the suggested answer indicates the force is directed upwards. Clarification is needed on the application of the left-hand rule and the orientation of the fingers. Understanding the correct application of these principles is essential for accurately determining the magnetic force direction.
