hay mate here is your answer

An electromagnet is a manmade device that acts almost exactly like a natural magnet. It has north and south poles that attract and repel north and south poles on natural magnets. It can attract certain kinds of of metals to it. The primary differences between an electromagnet and a natural magnet are the materials each is made of and the fact that when an electromagnet's power is switched off it loses its magnetic abilities, according to the National High Magnetic Field Laboratory.

The Electromagnetic Effect

As the Danish physicist Hans Christian Oersted discovered in the early 19th century, magnetic fields are caused by electric currents. While working in his laboratory, he discovered that all wires with a current flowing through them were able to affect compass needles as if they were magnets. This was called the electromagnetic effect, states MAGCRAFT Rare Earth Magnets.

The Source of Magnetic Fields in Nature

The atoms that make up natural magnets (like all atoms) are made of tiny negative electric charges called electrons, surrounding tiny positive electric charges called protons. The electrons are spinning and moving around their atoms, and this makes them small currents. The electrons of all atoms therefore generate tiny magnetic fields.

Permanent Magnets

According to the National High Magnetic Field Laboratory, in most substances these magnetic fields are pointing in every direction, so that all of these tiny magnetic fields usually don't add up to anything, because they work against one another too much. In some materials the fields can line up and act with one another, which gives the object a powerful magnetic field. Such objects are called magnets. Permanent magnets are always made of substances like magnetite, iron, nickel, or neodymium

Answer:

An electromagnet is a temporary magnet as its magnetic behaviour lasts for as long as the current flows through it..
