magnetic field
A physical force field generated by moving electric charges or magnetic materials that exerts a force on other magnets or moving charges.
Die Erde ist von einem Magnetfeld umgeben, das uns vor kosmischer Strahlung schützt.
The Earth is surrounded by a magnetic field that protects us from cosmic radiation.
The word is composed of 'Magnet' (magnet) and 'Feld' (field). So it literally describes a field that is generated by a magnet or has magnetic properties.
Ein Kompass richtet sich nach dem Magnetfeld der Erde aus.
A compass aligns itself with the Earth's magnetic field.
Common adjectives are 'stark' (strong), 'schwach' (weak), or 'elektromagnetisch' (electromagnetic). Typical verbs are 'ein Magnetfeld erzeugen' (to generate a magnetic field), 'messen' (to measure), or 'beeinflussen' (to influence).
Durch den Stromfluss wird ein starkes Magnetfeld erzeugt.
A strong magnetic field is generated by the flow of current.
This word belongs to the technical language of physics and engineering. In everyday life, it is usually used only in connection with the Earth's magnetic field or in scientific documentaries.
Im Physikunterricht haben wir über Magnetfelder gesprochen.
In physics class, we talked about magnetic fields.
field of tension
'Spannungsfeld' and 'Magnetfeld' can both refer to a field in physics, meaning a space in which forces act. 'Magnetfeld' is specifically the field created by magnets or moving electric charges. 'Spannungsfeld' can have to do with electrical or magnetic forces in physics, but it is also very often used figuratively: then it means a situation with opposing interests or opinions. That is why the words can be confused if you only think of 'field' and forces. For magnetism, 'Magnetfeld' is the precise word. For conflicts between interests, 'Spannungsfeld' fits.
Im Physikunterricht zeichnet Tara das Magnetfeld um einen Magneten.
In physics class, Tara draws the magnetic field around a magnet.
Die Firma steht im Spannungsfeld zwischen niedrigen Preisen und guter Qualität.
The company is caught in the field of tension between low prices and good quality.
