← A straight conductor 0.58 m long moves at 4.6 m/s across a field of 0.034 T, with the field, the length and the velocity at right angles to each other. What emf is induced between its ends?
**Assertion (A):** The core of a transformer is made of thin iron sheets, insulated from each other. **Reason (R):** Thin insulated sheets reduce the eddy currents in the core. →
