$\huge\mathfrak\red{☟ \: \: \: answer \: \: \: \: ✎}$

As the name suggests permanent magnet magnetic field is permanent and electromagnets magnetic field depends upon the flow of the electrical current. The electromagnet constitutes a coil made of wire which acts as a magnet when current is passed through it. Usually, a ferromagnetic material like steel is wrapped by an electromagnet to enhance its magnetic field.

The key difference between an electromagnet and a permanent magnet is that the electromagnet can have a magnetic field when an electric current flows through it and disappears when the flow of the current stops, while permanent magnets are made up of magnetic material that can be easily magnetized and can create.
