Consider the following statements regarding thermoelectric effects and magnetic fields: 1. The Seebeck effect involves the generation of an electric potential difference across the junction of two dissimilar metals maintained at different temperatures. 2. Fleming left-hand rule is used to determine the direction of force experienced by a current-carrying conductor placed in a magnetic field. Which of the statements given above is/are correct?

💡 Solution & Explanation

Both statements are fundamentally correct principles of electromagnetism and thermoelectricity. The Seebeck effect forms the working principle behind thermocouples used for precise temperature measurement, while Fleming left-hand rule correlates magnetic field direction, conventional current direction, and resulting mechanical force in electric motors. Thermoelectric generation converts thermal gradients directly into electrical energy without moving mechanical components.
