Web10 aug. 2024 · Solution: 2. The magnitude of the induced emf in a coil is directly proportional to the rate of change of flux linkages. This is known as A. Joule’s Law B. Faraday’s second law of electromagnetic induction C. Faraday’s first law of electromagnetic induction D. Coulomb’s Law View Answer: Answer: Option B Solution: 3. WebThe direction of induced EMF is physical. The induced currents flow in the opposite direction to the currents that created them. The right hand rule is valid if you consider the induced currents and the reaction magnetic field (the reaction field tends to reduce the source field, so they have opposite directions).
