1. Solenoid

솔레노이드는 촘촘히 감긴 코일 도선에 흐르는 전류가 만드는 자기장입니다. 솔레노이드 내부의 자기장은 균일하며 솔레노이드 축과 평행합니다. 이상적인 솔레노이드의 경우 외부 자기장은 거의 0에 수렴하며, 솔레노이드 내부 자기장의 방향은 오른손 규칙으로 정할 수 있습니다. 솔레노이드 내부 자기장의 크기는 Ampere의 법칙을 이용하여 계산할 수 있습니다.
2. Toroid

토로이드는 솔레노이드를 구부려 양 끝을 붙인 속이 비어 있는 팔찌 모양의 도선입니다. 토로이드 내부에 생기는 자기장은 Ampere의 법칙과 팔찌의 대칭성으로부터 구할 수 있습니다. 토로이드 내부 자기장의 크기는 토로이드 도선에 흐르는 전류와 감긴 횟수의 곱에 비례합니다.

1. Solenoid

Solenoids are an important electromagnetic device that have a wide range of applications in various fields. They consist of a coil of wire wrapped around a cylindrical core, typically made of a ferromagnetic material. When an electric current flows through the coil, it generates a magnetic field inside the solenoid, which can be used to create a linear motion or to produce a strong magnetic field. Solenoids are commonly used in electrical switches, relays, valves, and other electromechanical devices. They are known for their reliability, simplicity, and cost-effectiveness, making them a popular choice in many industrial and consumer applications. The strength of the magnetic field produced by a solenoid is directly proportional to the number of turns in the coil and the current flowing through it, allowing for precise control and adjustment of the magnetic force. Overall, solenoids are a versatile and essential component in many modern technologies and engineering applications.
2. Toroid

Toroids are a unique type of electromagnetic device that have a circular or donut-shaped structure. Unlike solenoids, which have a linear magnetic field, toroids generate a magnetic field that is confined within the toroidal core. This makes them particularly useful in applications where a localized and controlled magnetic field is required, such as in transformers, inductors, and certain types of sensors. Toroids offer several advantages over other electromagnetic designs, including higher efficiency, reduced electromagnetic interference, and improved safety due to the contained magnetic field. They are commonly used in power supplies, audio equipment, and various electronic circuits. The toroidal shape also allows for a more compact and space-efficient design compared to traditional transformer configurations. Additionally, the closed-loop structure of a toroid can provide better magnetic shielding and reduced stray magnetic fields, making them suitable for applications where electromagnetic compatibility is a concern. Overall, toroids are a versatile and important component in many electrical and electronic systems, offering unique advantages in terms of performance, efficiency, and design flexibility.
