← ScienceWhich outcome results when introducing a conductive object into a strong, rapidly alternating magnetic field?
A)Eddy current formation and heating✓
B)Dielectric polarization and breakdown
C)Thermoelectric voltage generation
D)Paramagnetic alignment and saturation
💡 Explanation
When a conductive object enters a rapidly alternating magnetic field, induced EMF generates circulating eddy currents due to Faraday's law of induction, causing resistive heating within the object. Therefore, eddy current formation and heating results, rather than polarization, thermoelectricity, or paramagnetism which require different material properties or field conditions.
