The correct Answer is:
To solve the assertion-reason question, we need to analyze both the assertion and the reason provided. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that "The direction of induced e.m.f. is always such as to oppose the change that causes it." This is a statement of Lenz's Law, which is a fundamental principle in electromagnetism. According to Lenz's Law, the induced electromotive force (e.m.f.) will always act in a direction to oppose the change in magnetic flux that produced it. - **Conclusion**: The assertion is **correct**. 2. **Understanding the Reason**: - The reason states that "The direction of induced e.m.f. is given by Lenz's Law." This is also true. Lenz's Law provides the rule for determining the direction of the induced e.m.f. based on the change in magnetic flux. - **Conclusion**: The reason is also **correct**. 3. **Combining the Assertion and Reason**: - Since both the assertion and the reason are correct, we need to determine if the reason correctly explains the assertion. In this case, the reason does explain the assertion because Lenz's Law directly relates to the direction of the induced e.m.f. opposing the change in magnetic flux. - **Final Conclusion**: Both the assertion and reason are correct, and the reason correctly explains the assertion. ### Final Answer: Both the assertion and reason are correct, and the reason correctly explains the assertion. ---

Electromagnetic brakes work on the principle of electromagnetic induction. If a metallic disc or a coil is rotating in a uniform magnetic field, it will experience a torque due to induced currents set up in the disc. According to Lenz's law, induced current is in a direction so as to oppose the rotation. Hence a retarding torque is produced. The rotating wheel of a vehicle is connected to a coil placed in a uniform emf is used to charge a battery. Thus kinetic enery of wheel is stored as chemical energy. The drawback of electromagnetic brake is that induced current or retarding torque is directly proportional to speed of rotation. The speed, therefore, decays exponentially and vehicle will take a long time to stop. Thus, mechanical brakes are used simultaneously. The advantage of electromagnetic brakes is that
