Self-induction (Noun)
Meaning
Generation of an electromotive force (EMF) in a circuit by changing the current in that circuit; usually measured in henries.
Classification
Nouns denoting natural phenomena.
Examples
- The coils of the transformer exhibited significant self-induction due to the changes in current flowing through them.
- Self-induction was discovered by Michael Faraday in 1831 when he found that an electromotive force was generated in a closed loop of wire by changing the current in the loop.
- The inductance of the circuit was directly proportional to the self-induction of the coil, which in turn depended on the number of turns of wire and the area of the coil.
- The researchers measured the self-induction of the circuit by observing the voltage induced across the coil when the current was changed.
- The high self-induction of the electromagnet meant that it resisted changes in current, resulting in a delay in the response of the magnet's field to changes in the input voltage.
