← ScienceWhich consequence results when a pulsed electromagnet's frequency matches ferromagnetic material's resonant frequency?
A)Material experiences magnetic domain resonance✓
B)Electromagnet power supply overheats rapidly
C)Induced eddy currents reduce drastically
D)Electromagnetic wave propagates isotropically
💡 Explanation
Magnetic domain resonance maximizes energy transfer, because a frequency match causes enhanced domain oscillations. Therefore, material experiences strong heating and magnetization changes, rather than reduced eddy currents, overheating the power supply or isotropic wave propagation.
