← ScienceWhich phenomenon creates eddy currents within a metallic conductor exposed to an alternating magnetic field?
A)Electromagnetic induction converting energy✓
B)Capacitive discharge storing charge
C)Thermoelectric effect generating voltage
D)Piezoelectric effect producing vibration
💡 Explanation
When a metallic conductor is placed in an alternating magnetic field, electromagnetic induction occurs because the changing magnetic flux induces circulating currents within the conductor. Therefore eddy currents result, rather than other electrical effects needing different conditions.
