FAQs on Toroid Video Lecture - Physics Class 12 - NEET

1. What is a toroid?
Ans. A toroid is a geometric shape that resembles a donut or a tire tube. It is formed by revolving a circle around an axis that is coplanar with the circle. In other words, it is a three-dimensional figure with a hole in the middle.
2. How is a toroid different from other geometric shapes?
Ans. Unlike other geometric shapes, a toroid has a hole in the middle, which sets it apart. This unique feature gives it various applications, such as in transformers, electromagnets, and particle accelerators.
3. What are some common uses of toroids in electrical engineering?
Ans. Toroids find extensive use in electrical engineering. They are commonly employed in transformers to improve energy efficiency and reduce electromagnetic interference. Toroidal inductors are also used for filtering out high-frequency noise in electronic circuits.
4. How does a toroid help in reducing electromagnetic interference?
Ans. The toroidal shape of a core in a transformer or inductor helps confine the magnetic field inside the core, reducing the electromagnetic interference emitted outside. This property makes toroids ideal for applications where electromagnetic compatibility is essential.
5. Can toroids be used in particle accelerators?
Ans. Yes, toroids are often used in particle accelerators to create a magnetic field that guides and focuses charged particles along their desired path. The circular magnetic field generated by the toroid helps maintain the particle's trajectory and control its movement.
