Magnetism and electromagnetism are related because electromagnetism is a branch of physics that deals with the interaction between electric currents and magnetic fields. When an electric current flows through a conductor, it creates a magnetic field around it, resulting in electromagnetism. This relationship is fundamental in understanding how devices like electric motors and generators work.

Studying electromagnetism is crucial because it helps us understand the fundamental forces at play in the universe. It has led to the development of technologies like electric power generation, motors, and communication devices. Additionally, electromagnetism forms the basis of many other branches of physics, such as optics and quantum mechanics.
if a component has an electrical connection and movement is created by or within the component, then that component will use an electromagnet. Devices such as relays, solenoids and motors, use electromagnets to create movement. Ignition coils and transformers use electromagnetic induction to raise or lower voltage outputs
Electromagnetism has created many changes in the fields of engineering, space, medicine, and more. One of the more ubiquitous uses of electromagnetism is its ability to allow us to simply switch electricity on and off as needed.
Electromagnetism is good for humans because it enables technologies like electricity, communication devices, and medical equipment. However, exposure to excessive electromagnetic fields from sources like high-voltage power lines or electronic devices may have potential health risks, such as an increased risk of certain cancers or other health issues.
There are many devices that make use of wireless charging technology. Some electronic toothbrushes use this technology to recharge as do some electric cars from General Motors and Toyota. Some smart phones also use this technology.
Devices that use wi-fi technology are typically mobile devices. Examples of these devices include laptops, e-readers, tablets, mobile phones and smartphones. Other devices, such as computers and televisions, may also use wi-fi technology.
