What is Magnetism?
Magnetism is a type of force that exists between particles that have an electrical charge These particles can either be positively or negatively charged, and they tend to attract or repel each other. Magnets are materials that contain an abundance of particles with an electrical charge, which can induce an attractive or repulsive force known as a magnetic field. Magnetic fields can be used to move objects, create energy, and manipulate other forces in the environment.
Magnetism has been a topic of interest for centuries. Ancient civilizations discovered lodestone, which is a naturally occurring magnetic material that can be used to create a compass. By understanding how magnetism works, scientists have been able to create powerful machines and technologies such as turbines, speakers, and cell phones.
