The correct Answer is:
To solve the given question, we need to analyze the two statements provided: **Statement 1:** When the current decreases in a conducting loop placed coaxially with a similar loop without current, they attract each other. **Statement 2:** As the current in one loop decreases, an induced current starts flowing in the same sense in the other loop. ### Step-by-Step Solution: 1. **Understanding the Setup:** - We have two coaxial conducting loops. One loop has a current flowing through it (let's call it Loop A), and the other loop (Loop B) does not have any current initially. 2. **Current Decrease in Loop A:** - When the current in Loop A decreases, the magnetic field generated by Loop A also decreases. This is due to the relationship between current and magnetic field, where the magnetic field strength is directly proportional to the current flowing through the loop. 3. **Change in Magnetic Flux:** - The decrease in the magnetic field leads to a decrease in magnetic flux through Loop B. According to Faraday's law of electromagnetic induction, a change in magnetic flux through a loop induces an electromotive force (emf) in that loop. 4. **Induced Current in Loop B:** - Because the magnetic flux through Loop B is decreasing, an induced current will flow in Loop B. According to Lenz's law, the direction of the induced current will be such that it opposes the change in magnetic flux. Since the magnetic flux is decreasing, the induced current in Loop B will flow in the same direction as the current in Loop A to try to maintain the magnetic flux. 5. **Attraction Between the Loops:** - When both loops have currents flowing in the same direction (Loop A's original current and Loop B's induced current), they will attract each other. This is a fundamental principle of electromagnetism: parallel currents attract. 6. **Conclusion:** - Therefore, Statement 1 is true because the loops attract each other when the current in Loop A decreases. Statement 2 is also true as it correctly explains why the induced current flows in the same direction in Loop B. ### Final Answer: - **Both statements are true, and Statement 2 is the correct explanation for Statement 1.** ---
