relating to electric and magnetic fields
Connected with both electricity and magnetism at the same time, especially in science and physics.
Vzorec užití:
electromagnetic [field/wave/radiation/force]
Častá chyba:
Learners often confuse "electromagnetic" with "electric" or "electronic". "Electric" usually means powered by electricity (an electric car), and "electronic" refers to devices that use complex circuits and chips (an electronic watch). "Electromagnetic" is more technical and refers to phenomena that involve both electricity and magnetism, such as electromagnetic waves or electromagnetic fields.
Synonyma
electromagnetism-related (More descriptive and less standard; explicitly mentions the underlying theory but used mainly in explanations, not set phrases.)
Antonyma
mechanical (Refers to motion and physical forces of solid objects, contrasting with phenomena described mainly by electric and magnetic fields.)

operated by an electromagnet
Working by using an electromagnet or electromagnetic force inside a machine or tool.
Vzorec užití:
electromagnetic [brake/lock/actuator/valve]
Častá chyba:
Learners may think this meaning is always abstract physics, but here it is concrete: the word describes devices that physically use electromagnets to work (for example, a door lock or brake). Another confusion is with "magnetic" devices that use permanent magnets; "electromagnetic" devices specifically use magnets powered by electric current.
Synonyma
electromagnet-powered (More explicit and informal; clearly states that an electromagnet provides the power or action, but is less common in technical writing.)
Antonyma
manual (Indicates something operated directly by a person’s physical effort, not by an electromagnet or other automatic system.)
