Explanation:
A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field. As the name suggests, a permanent magnet is 'permanent'. This means that it always has a magnetic field and will display a magnetic behavior at all times.
An electromagnet is made from a coil of wire which acts as a magnet when an electric current passes through it.
