  • The strength of the electromagnet was specified as 500 ampere-turns.

Examples

  • Increasing the number of ampere-turns enhances the magnetomotive force in the coil.

  • The motor requires 10 ampere-turns to operate efficiently.

  • The calculation required converting gilberts into ampere-turns for comparison.

  • An ampere-turn is a basic unit in magnetism.

  • Increasing the number of ampere-turns in the coil enhances its magnetomotive force.

  • The electromagnet in the experiment produces a force of 300 ampere-turns.

  • To achieve effective results, you need at least 5 ampere-turns for the circuit design.

Morphology

ampere-turn = ampere + turn (transparent) = ampere + turn

The term is a straightforward technical compound of 'ampere' + 'turn'; its meaning follows directly from the component units.

Etymology

The word ampere-turn combines ampere, the unit of electric current named after the French scientist André-Marie Ampère and often shortened to 'amp', and turn, meaning 'a loop of wire'. So an ampere-turn is simply the magnetic effect of one 'amp' flowing through one 'turn', which is why it measures the strength of a coil's magnetic force.
