Context: "physics"
(noun) in physics, a toroid can refer to a coil of wire shaped like a doughnut. This is used in devices like transformers and inductors. When electricity flows through it, it creates a magnetic field.
Example
The engineer designed a toroid to improve the efficiency of the electrical circuit.
Example
The circuit did not work well without the toroid; a straight wire would not create the same effect.
Example
How does the toroid help in producing a magnetic field?
