摘要

本文推导了磁摆的电磁（EM）场表达式。机械频率和磁偶极矩是通过应用机械动力理论求得的。对表达式的研究表明，电磁场包含基波和高阶谐波，这与具有简谐运动的磁体截然不同，它们的振幅比受第一类贝塞尔函数支配。实验验证使用了 1 赫兹辐射器系统。文中详细讨论了摆锤的辐射模式、效率和 Q 因子。本文提供了摆锤天线的理论基础和实验验证。

Study of the electromagnetic field generated by a magnetic pendulum

In this paper the electromagnetic (EM) field expressions for a magnetic pendulum are derived. The mechanical frequency and the magnetic dipole moment are found by applying mechanical-kinetic theory. A study of the expressions reveals that the electromagnetic field contains both the fundamental and higher order harmonic waves, which is quite different from a magnet with simple harmonic motion, and their amplitude ratios are governed by Bessel Functions of the first kind. 1 Hz radiator system is used for the experimental verification. The radiation pattern, the efficiency and the Q factor of the pendulum are discussed in detail. This paper provide the theoretical basis with the experimental verification of the pendulum antenna.

期刊介绍： Results in Physics is an open access journal offering authors the opportunity to publish in all fundamental and interdisciplinary areas of physics, materials science, and applied physics. Papers of a theoretical, computational, and experimental nature are all welcome. Results in Physics accepts papers that are scientifically sound, technically correct and provide valuable new knowledge to the physics community. Topics such as three-dimensional flow and magnetohydrodynamics are not within the scope of Results in Physics. Results in Physics welcomes three types of papers: 1. Full research papers 2. Microarticles: very short papers, no longer than two pages. They may consist of a single, but well-described piece of information, such as: - Data and/or a plot plus a description - Description of a new method or instrumentation - Negative results - Concept or design study 3. Letters to the Editor: Letters discussing a recent article published in Results in Physics are welcome. These are objective, constructive, or educational critiques of papers published in Results in Physics. Accepted letters will be sent to the author of the original paper for a response. Each letter and response is published together. Letters should be received within 8 weeks of the article''s publication. They should not exceed 750 words of text and 10 references.
