1. Helmholtz Coil

실험 1에서는 헬름홀츠코일의 축 위에서 자기장을 측정하여, 위치에 따른 자기장의 세기를 측정하고, 자기장의 세기의 균일한 정도를 관찰하였다. 비오-사바르 법칙을 이용하여 헬름홀츠 코일의 자기장의 세기를 계산하였고, 두 코일사이의 거리가 코일의 반지름일 때 자기장의 변화가 가장 균일한 것을 확인하였다. 실험 데이터 분석 결과, 10cm 조건에서 자기장의 세기 변화가 가장 완만한 것을 관찰할 수 있었다. 그러나 실험실 환경상 측정에 있어 여러 한계가 존재하여 정밀한 값을 측정하기 어려웠다.
2. Faraday's Law

실험 2에서는 페러데이법칙을 이용하여 유도기전력을 측정하는 실험을 진행하였다. field coil에 교류전류가 흐르면 detector coil에는 그 교류전류의 도함수 모양의 전류가 유도되는 것을 확인할 수 있었다. 실제 데이터 분석 결과, field coil에 sine파가 흐를 때 detector coil에는 π/2의 위상차가 발생한 cos함수 파형이 유도되었다. 또한 field coil의 자체유도계수를 구하여 전류값을 계산하고 유도기전력을 구한 값과 실제 데이터값을 비교해 보면 큰 차이가 나는 것을 관찰할 수 있었다. 이는 detector coil을 완벽하게 정렬하지 못했기 때문으로 생각된다.

1. Helmholtz Coil

The Helmholtz coil is a device used to generate a uniform magnetic field in a specific region of space. It consists of two circular coils placed coaxially and separated by a distance equal to the radius of the coils. This configuration allows for the creation of a highly uniform magnetic field in the space between the coils, which is useful for various applications such as magnetic field calibration, particle beam steering, and magnetic resonance imaging (MRI) systems. The key advantage of the Helmholtz coil is its ability to produce a highly uniform magnetic field over a relatively large volume. This is achieved by carefully designing the coil geometry and the current flowing through the coils. The uniform magnetic field is essential for many scientific and engineering applications where a controlled and stable magnetic environment is required. In addition to its practical applications, the Helmholtz coil is also an important tool in the study of electromagnetism and the behavior of charged particles in magnetic fields. It allows researchers to investigate the fundamental principles of electromagnetism and to validate theoretical predictions through experimental observations. Overall, the Helmholtz coil is a versatile and widely used device that has made significant contributions to various fields of science and technology. Its ability to generate a uniform magnetic field has enabled numerous advancements and continues to be an important tool in both research and practical applications.
2. Faraday's Law

Faraday's law of electromagnetic induction is a fundamental principle in electromagnetism that describes the relationship between a changing magnetic field and the induced electromotive force (EMF) in a conductive material. This law, formulated by the English scientist Michael Faraday in the 19th century, has had a profound impact on our understanding and application of electromagnetic phenomena. According to Faraday's law, the induced EMF in a conductive loop or circuit is directly proportional to the rate of change of the magnetic flux passing through the loop. This means that when a magnetic field changes over time, it induces an electric field that can drive a current in a conductive material. This principle is the foundation of many important technologies, such as electric generators, transformers, and electric motors. Faraday's law has far-reaching implications in various fields, including physics, engineering, and technology. It explains the operation of many electrical devices and systems, and it has enabled the development of numerous applications that rely on the conversion of energy between electrical and magnetic forms. Moreover, Faraday's law is not only a practical tool but also a fundamental concept in the study of electromagnetism. It helps us understand the underlying mechanisms of electromagnetic induction and the behavior of charged particles in changing magnetic fields. This understanding has been crucial for advancing our knowledge of the physical world and for developing new technologies that harness the power of electromagnetism. In conclusion, Faraday's law of electromagnetic induction is a cornerstone of our understanding of electromagnetism and has had a profound impact on the development of modern technology. Its significance extends far beyond its practical applications, as it continues to shape our understanding of the fundamental principles governing the interaction between electricity and magnetism.
