Well, it's a shocking revelation, but the answer is electric current. Without that zapping through the coiled wire, there wouldn't be any magnetic force to attract or repel. So you could say it's the power behind the magnet's field. Keep the laughter current flowing!
The magnetic force in an electromagnet is created by the electric current flowing through the coiled wire.
The correct answer is: electric current.
Explanation: An electromagnet creates a magnetic force when an electric current flows through a coiled wire. When an electric current passes through a wire, it creates a circular magnetic field around the wire. This magnetic field can be intensified by placing an iron or steel core inside the coil. The iron or steel core increases the strength of the magnetic field by redirecting the magnetic field lines and channeling them through the core, creating a stronger magnetic force. The source that provides the electric current, such as a battery, is necessary to produce the magnetic force in an electromagnet.
