electromagnetic
Meaning: Relating to the interrelation of electric currents and magnetic fields, or to radiation comprising both electric and magnetic wave components, such as light, radio waves, and X-rays.
Electromagnetic is one of the foundational adjectives of modern physics and engineering. It collocates with spectrum, radiation, field, pulse, wave, and interference. The electromagnetic spectrum — from radio waves through visible light to gamma rays — is a standard reference framework in science education. In defence and technology journalism, electromagnetic pulse (EMP) and electromagnetic interference (EMI) appear frequently. The term is also used in discussions of health concerns about electromagnetic fields from power lines and mobile phone masts.
Examples
- The electromagnetic spectrum encompasses everything from long-wave radio signals to short-wavelength gamma radiation. 电磁波谱涵盖了从长波无线电信号到短波长伽马射线的一切。El espectro electromagnético abarca desde las señales de radio de onda larga hasta la radiación gamma de longitud de onda corta.電磁スペクトルは、長波の電波信号から短波長のガンマ線までを包括する。전자기 스펙트럼은 장파의 전파 신호부터 단파장의 감마선까지를 포괄한다.
- Concerns about electromagnetic interference led regulators to require shielding on all sensitive medical equipment. 出于对电磁干扰的担忧,监管机构要求对所有敏感医疗设备进行屏蔽。La preocupación por las interferencias electromagnéticas llevó a los reguladores a exigir el apantallamiento de todos los equipos médicos sensibles.電磁干渉への懸念から、規制当局はすべての精密医療機器にシールドを義務付けた。전자기 간섭에 대한 우려로 규제 당국은 모든 민감한 의료 장비에 차폐를 의무화했다.
- Maxwell's equations unified the theories of electricity and magnetism into a single electromagnetic framework. 麦克斯韦方程组将电学和磁学理论统一为一个单一的电磁学框架。Las ecuaciones de Maxwell unificaron las teorías de la electricidad y el magnetismo en un único marco electromagnético.マクスウェルの方程式は、電気と磁気の理論を一つの電磁気学的枠組みに統一した。맥스웰 방정식은 전기와 자기의 이론을 하나의 전자기학적 체계로 통일했다.
