Hey J6ss🫡🫡, good to see you again. Here are the answers to your physics questions. Part 1: Completing the table To complete the table, we use Fleming's Left-Hand Rule (Motor Rule): Forefinger: Magnetic field direction Middle finger: Current direction Thumb: Force/Movement direction From the diagram: The roller moves horizontally (directions 'x' or 'y'). This implies the force is horizontal. The current flows through the roller, which is horizontal. For a horizontal current and horizontal force, the magnetic field must be vertical* (up or down). Current direction: Switch P: Current flows from the top rod, through the roller, to the bottom rod. Let's assume this means current flows into the page* through the roller. Switch Q: Current flows from the bottom rod, through the roller, to the top rod. Let's assume this means current flows out of the page* through the roller. Magnet position (A, B, C, D): We assume these positions alternate the magnetic field direction between 'up' and 'down'. A and C: Magnetic field is up*. B and D: Magnetic field is down*. Applying Fleming's Left-Hand Rule: | Magnet position | Switch position | Magnetic field direction | Movement of roller | | :-------------- | :-------------- | :----------------------- | :----------------- | | A | P | up | x | | B | P | down | y | | C | P | up | x | | D | P | down | y | | A | Q | up | y | | B | Q | down | x | | C | Q | up | y | | D | Q | down | x | Part 2: Question 4 a) When the switch is closed, conductor PQ experiences a force. In which direction is this force? Step 1: Identify the directions of the magnetic field and current. The magnetic field is stated as upwards (out of the page). When the switch is closed, current flows from the positive terminal of the battery, through runner X, through conductor PQ (from P to Q), through runner Y, and back to the negative terminal. So, the current in PQ is to the right. Step 2: Apply Fleming's Left-Hand Rule. Forefinger (Field): Out of the page. Middle finger (Current): To the right. Thumb (Force): Points upwards*. The force is in the upwards direction. b) State two ways to reverse the direction of movement of the conductor, PQ. To reverse the direction of the force, you must
