Voltransistor

After the current builds up in the coils, it collapses the magnetic field and raises the voltage enough to blow em up.

Voltage spike, short answer. Just like Voltransistor said. Transformers are not much good for dc use unless you intend to make a electrical magnet. Even when intended for a electro magnet dc will burn the coil right away or after some time.

The tranfsormer acts as a coil : when a coil is powered, it creates a magnetic field. When you sufdently remove the coil's power (switching), the magnetic field go througth the coil and creates a reverse current (a voltage spike). This is used in gasoline engines : coils quickly switched in and off creates voltages spikes (~ 10 kV) and that's making sparks.
