magnetic induction
- noun
- /mæɡˈnɛtɪk ɪnˈdʌkʃən/
- Specialized
- When a metal is placed in a magnetic field, it can experience magnetic induction, causing it to become magnetized.
It was only the change that caused magnetic induction.
- It was only the change that caused magnetic induction.
Examples
-
The concept of magnetic induction helps explain how wireless charging devices can transfer power without physical connections.
-
When electricity is generated by magnetic induction, a conductor is in a magnetic field and there is relative motion between the two, resulting in current.
Academic text (2011) -
Subsequent amplification of a magnetic field can happen in many situations, all of which are a consequence of the magnetic induction equation for plasmas that can be straightforwardly derived from the Maxwell equations and Ohm's law.
Academic text (2002) -
Electric generators operate based on magnetic induction, where motion between a magnet and a conductor induces electrical current.
Synonyms
A process that makes a material attract iron, sometimes temporarily or forever

Morphology
The compound is compositionally built from 'magnetic' (having magnetism) and 'induction' (a process of producing something), so the meaning — a process by which magnetism is produced or a material becomes magnetized — is directly inferable from the parts. This follows ordinary noun–noun compounding and is cross-linguistically regular in technical contexts, so a B1 learner who knows both constituents should be able to understand it.
Etymology
Magnetic induction pictures a magnet giving magnetic power to something near it. The word magnetic shows the magnet and induction comes from the idea 'to cause' or 'bring about', so the phrase means the magnet makes the material act like a magnet.
