An electromagnet does not function without a source of current.
An electromagnet functions because of the electric current used to generate the magnetic field
<h2>Further Explanation </h2><h3>Magnet </h3>
A magnet is an object that possess magnetic field and thus attracts certain materials when they are brought near it. Materials attracted by a magnet are known as magnetic materials while those that are not attracted by a magnet are known as no-magnetic materials.
A magnet contains two poles that is the North Pole and the South Pole. Magnetic field lines run from the south towards the North Pole.
<h3>Electromagnet
</h3>
An electromagnet is a type of magnet that is made from electric current. This is done by passing electric current through a solenoid which surrounds a magnetic material such as soft iron.
An electromagnet depends on the electric current passed through the material used to make it, such that when the electric current is withdrawn then the magnetism is lost.
Additionally, an increase in the amount of electric current increases the strength of the electromagnet and vice versa.
Electromagnets are made from coils of electrical wires carrying electric current. A magnetic material such as soft iron is then placed inside the coil, resulting to the creation of magnetic fields with north and south poles.
Electromagnets have a wide variety of uses such as in speakers, motors, generator and other many kinds of electric devices.
