The Motor Effect and Fleming's Left-Hand Rule
This animation shows a current-carrying wire placed in an external magnetic field, illustrating how the two fields interact to produce a physical force on the wire. It visually demonstrates Fleming's Left-Hand Rule for finding the direction of motion, and shows how force magnitude is calculated as field strength multiplied by current and wire length. Designed for 10th grade physics students studying electromagnetism and force interactions.

The prompt that made it
The motor effect occurs when a current-carrying wire experiences a physical force due to the interaction between its own magnetic field and an external magnetic field. The resulting directional movement can be determined using Fleming's Left-Hand Rule, with the magnitude of the force calculated by multiplying the field strength, current, and wire length. Audience: 10th grade science students
