electromagnetic
Refers to the physical phenomena that arise from the interaction of electric and magnetic fields.
Mobiltelefone nutzen elektromagnetische Wellen, um Signale zu übertragen.
Mobile phones use electromagnetic waves to transmit signals.
The word is made up of 'elektro-' (from elektrisch, meaning electric) and 'magnetisch' (magnetic). So it describes something that has both electric and magnetic properties.
Ein Kompass reagiert auf das elektromagnetische Feld der Erde.
A compass reacts to the Earth's electromagnetic field.
This adjective is almost always combined with technical terms from physics. The most common combinations are 'elektromagnetische Wellen' (electromagnetic waves), 'elektromagnetisches Feld' (electromagnetic field), and 'elektromagnetische Strahlung' (electromagnetic radiation).
Licht ist eine Form von elektromagnetischer Strahlung.
Light is a form of electromagnetic radiation.
'Elektromagnetisch' (electromagnetic) is a technical term from physics and engineering. You will find it mainly in scientific, technical, or educated-language texts.
Im Physikunterricht lernten wir über elektromagnetische Induktion.
In physics class, we learned about electromagnetic induction.
electric
'elektrisch' and 'elektromagnetisch' both belong to the area of physics and technology. 'elektrisch' is the more general word: it fits when something is powered by electricity or connected with electricity. 'elektromagnetisch' is more specific and refers to processes in which electric and magnetic fields interact. The words can be confused because electromagnetic processes also have to do with electricity. In everyday language, people usually say 'elektrisch'; in technical or physics explanations, 'elektromagnetisch' is more likely.
Im Physikunterricht erklärt die Lehrerin elektromagnetische Wellen.
In physics class, the teacher explains electromagnetic waves.
Mein Vater fährt seit diesem Jahr ein elektrisches Auto.
My father has been driving an electric car since this year.
