Which risk develops when exceeding a ferromagnetic material's coercive field?

💡 Explanation

Exceeding a ferromagnetic material's coercive field causes magnetization polarity to reverse abruptly because the applied field overcomes the energy barriers impeding domain wall motion; therefore, the material realigns itself rather than maintaining its original state. Options A, C and D refer to other effects.
