Zorluk: OrtaElectromagnetism and Induction

Match each electromagnetic device on the left with its correct operating principle or primary functional description on the right.

  • Electromechanical RelayUses an energized coil to pull a ferromagnetic armature, opening or closing separate electrical circuit contacts.
  • Linear SolenoidConverts an electromagnetic field into linear mechanical movement to pull or push a movable plunger.
  • Step-Up TransformerUses mutual induction to increase alternating voltage while proportionally decreasing alternating current.
  • Inductor CoilOpposes changes in electrical current by generating a self-induced counter-electromotive force (counter-EMF).

Cevap

Electromechanical Relay matches with using an energized coil to pull an armature to open or close circuit contacts; Linear Solenoid matches with converting an electromagnetic field into linear mechanical motion to actuate a plunger; Step-Up Transformer matches with using mutual induction to increase AC voltage while decreasing AC current; Inductor Coil matches with opposing changes in electrical current via self-induced counter-EMF.
Each electromagnetic device corresponds to a distinct electromagnetic mechanism: the relay magnetically toggles switch contacts; the solenoid converts magnetic fields into linear mechanical stroke; the step-up transformer uses mutual induction to increase AC voltage; and the inductor coil generates self-induced counter-EMF to oppose changes in current.

Adım Adım Çözüm

1
Identify the operating mechanism of an electromechanical relay
Matched to using an energized coil to pull a ferromagnetic armature and toggle electrical contacts.
Relays function as electrically operated switches, using electromagnetism to control contacts in a secondary circuit without direct electrical connection.
2
Identify the operating mechanism of a linear solenoid
Matched to converting magnetic flux into linear mechanical motion of an internal plunger.
Solenoids are actuators that translate electromagnetic coil energization into physical linear pushing or pulling work.
3
Identify the operating mechanism of a step-up transformer
Matched to using mutual induction to increase AC voltage while proportionally decreasing current.
Transformers rely on dynamic magnetic flux linkage between primary and secondary coils to scale alternating voltage levels according to turns ratios.
4
Identify the operating mechanism of an inductor coil
Matched to opposing current variations through self-induced counter-electromotive force.
According to Lenz's law and Faraday's law of self-induction, an inductor generates a counter-voltage that directly resists changes in the current passing through it.
