mutual inductance

Thân thiện

Two coils of wire are placed near each other to demonstrate mutual inductance.

Definition

1. Noun:
   • A measure of the induction between two circuits; the ratio of the electromotive force in a circuit to the corresponding change of current in a neighboring circuit; usually measured in henries. It is a quantitative property that describes how effectively a changing current in one coil or circuit induces a voltage in a nearby, separate coil or circuit.

Usage Examples

• Noun:
  • The mutual inductance between the primary and secondary coils determines the transformer's efficiency.
  • To calculate the induced voltage, you need to know the rate of change of current and the mutual inductance.
  • Engineers minimized the mutual inductance between the two wires to prevent signal interference.

Advanced Usage

• "Coefficient of mutual inductance": Another term for mutual inductance, emphasizing it as a constant of proportionality.
  • The coefficient of mutual inductance (M) for the two solenoids was calculated from their geometry.
• "Mutual inductance coupling": Refers to the interaction or linkage between circuits via mutual inductance.
  • The circuit's behavior is dominated by mutual inductance coupling between the resonant loops.

Variants and Related Words

• Mutual induction (n): The physical phenomenon or process by which a changing current in one circuit induces an electromotive force in a neighboring circuit. (Note: "Mutual inductance" is the of this phenomenon).
• Self-inductance (n): The induction of an electromotive force in a circuit by a changing current in the same circuit itself.
• Inductance (n): The broader property of an electrical conductor by which a change in current induces an electromotive force.

Synonyms

• Coefficient of mutual induction: A direct synonym.
• Mutual inductive coupling: Often used in engineering contexts to describe the effect.

Related Phrases

• To have a mutual inductance of [value]: Describes the specific quantitative relationship.
  • The two circuits have a mutual inductance of 5 millihenries.
• Mutual inductance is present between...: Describes the existence of the phenomenon.
  • Significant mutual inductance is present between the power line and the communication cable.
