When the electric current is switched off, the electromagnet loses its magnetic field, causing the metal material to no longer be attracted to the magnet. This results in the metal dropping off from the electromagnet due to the absence of the magnetic force that was previously holding it in place.
An electromagnet is switched on by passing an electric current through its coil, which generates a magnetic field. To switch it off, the current is simply disconnected, causing the magnetic field to collapse. This on/off switching allows for control of the magnetic force produced by the electromagnet.
A current carrying coil with an iron core creates an electromagnet. The iron core enhances the magnetic field strength produced by the coil, making it more effective for applications like electric motors, transformers, and solenoids.
When the electricity supplying an electromagnet is switched off, the magnetic field produced by the electromagnet disappears. This means that the electromagnet loses its magnetic properties and no longer attracts or repels magnetic materials.
A horseshoe electromagnet is an example of a temporary magnet because it only exhibits magnetic properties when an electric current is passed through it. When the current is turned off, the magnetism disappears.
A normal magnet is a static magnet that produces a magnetic field without needing an external power source. In contrast, an electromagnet is a magnet created by passing an electric current through a coil of wire, producing a magnetic field that can be turned on and off by controlling the electric current.
An electromagnet. Unlike other magnets it can be switched on and off.

Mainly in that the electromagnet is NOT permanent. In other words, it can be switched on and off.Another relevant difference is that the electromagnet constantly requires power, at least while it is on.
Basically, yes. However, especially when the electromagnet uses iron, it will most likely have some residual magnetism when the current is switched off. Note: You shouldn't used the word "charged" in this context. That refers to electrical charges, and is not usually used for magnetism.
Non-electric appliances.
One advantage of a natural magnet is that it does not require any external power source to maintain its magnetic properties, unlike an electromagnet that requires electricity to operate. Natural magnets are typically more stable and retain their magnetism for a longer period of time compared to electromagnets that can lose their magnetic properties when the electric current is removed.
