* Magnetic field collapses: The magnetic field generated by the flowing current instantly collapses. This is because the magnetic field is directly proportional to the current. With no current, there's no magnetic field.
* Magnetic force disappears: The force exerted by the electromagnet, which was responsible for attracting or repelling ferromagnetic materials, disappears.
* Electromagnet becomes inactive: The electromagnet essentially returns to its original state, no longer acting like a magnet.
In essence, switching off the current removes the "magnetic power" of the electromagnet. It's like turning off the switch for a light bulb – the bulb no longer emits light.
