← ScienceWhich risk increases within transformer cores under cyclical magnetization?
A)Core saturation decreases rapidly.
B)Hysteresis losses cause thermal runaway.✓
C)Eddystone currents minimize overall output.
D)Magnetostriction enhances core flexibility.
💡 Explanation
Hysteresis causes heat generation because the magnetic domains resist re-alignment, therefore the thermal energy cannot dissipate quickly in the core steel, rather than minimized current behavior in the primary coil during normal operating conditions.
