How do electromagnets differ from regular magnets?

Answer:

Permanent Magnets and Electromagnets: What are the Differences? A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field. ... An electromagnet is made from a coil of wire which acts as a magnet when an electric current passes through it.

Step-by-step explanation:

Electromagnets differ from regular magnets in that they require an electric current to generate a magnetic field.

Regular magnets, also known as permanent magnets, possess an inherent magnetic field due to the alignment of their atomic or molecular structure. They do not require an external power source.

On the other hand, electromagnets are made by wrapping a coil of wire around a magnetic core and passing an electric current through the wire. The electric current creates a magnetic field, and the strength of the magnetic field can be controlled by varying the current.

One key advantage of electromagnets is their ability to be turned on and off by controlling the electric current. This feature allows for a wide range of applications, such as in electric motors, generators, speakers, magnetic levitation systems, and more, where the magnetic field needs to be controlled or modulated. In contrast, regular magnets have a constant magnetic field that cannot be easily manipulated.
