In mathematics, a toroid is a surface of revolution with a hole in the middle. The axis of revolution passes through the hole and so does not intersect the surface. [1] . For example, when a rectangle is rotated around an axis parallel to one of its edges, then a hollow rectangle-section ring is produced.

Toroid is defined as the circular ring with numerous turns of enamelled wire. Learn about the difference between solenoid and toroid and their similarities. Also, learn about the magnetic field of toroid and its formula along with applications here.

A toroid is a donut-shaped coil closely wound with one continuous wire, as illustrated in part (a) of Figure \(\PageIndex{4}\). If the toroid has N windings and the current in the wire is I , what is the magnetic field both inside and outside the toroid?

The toroid is a useful device used in everything from tape heads to tokamaks. Finding the magnetic field inside a toroid is a good example of the power of Ampere's law. The current enclosed by the dashed line is just the number of loops times the current in each loop. Amperes law then gives the magnetic field by.

What is a Toroid? A toroid is a doughnut-shaped object, which in physics, particularly electromagnetism, refers to a coil of wire wound around a circular ring. This shape is crucial because it confines the magnetic field to its core. Imagine a doughnut or a ring-shaped cushion. A toroid is very much like that in shape.

The meaning of TOROID is a surface generated by a closed plane curve rotated about a line that lies in the same plane as the curve but does not intersect it.

2022年2月20日 · A toroid is a type of solid of revolution with the apperence of a hollow circular ring or a doughnut-shaped solid. A surface of revolution is created by revolving a plane curve about a straight line that lies in the same plane, the axis of rotation.

2024年9月19日 · A toroid is a fascinating geometric shape that is widely used in physics and engineering, particularly in the study of electromagnetism. Essentially, a toroid is a doughnut-shaped coil of wire, with a hollow center, where the wire is wound in a circular loop.

2025年1月26日 · A toroid is a doughnut-shaped object, often used in electrical circuits. It is essentially a hollow circular ring with numerous turns of a wire wound so closely that there is almost no space between the turns.

2023年6月11日 · A toroid is a donut-shaped magnetic coil, typically made of a ferromagnetic core wrapped with wire. Toroids are used in various electrical applications, including transformers and inductors, to create a compact and efficient magnetic field with minimal leakage.
