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.

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.

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 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.

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.

2022年9月4日 · A toroid is an electromagnetic device consisting of a conducting wire wound into a coil around a metallic core bent into the shape of a circle. It is similar to a solenoid except that it is bent. Like any other electromagnetic device, a toroid produces a magnetic field when current is sent through the wire.

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.

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.

2003年4月6日 · Toroids look exactly like doughnuts and come in various diameters, thicknesses, permeabilities and types depending upon the frequency range of interest. Includes links to Micrometals inductor design software and Micrometals RF design software." What are toroids? These come in two types. Powdered Iron or Ferrites.
