Products Description

1. Overview A Helmholtz coil is a pair of identical, co-axial, and parallel circular coils, each closely wound with N turns of wire. Due to its simple structure and ability to generate a magnetic field with high uniformity, it serves as a key component in magnetic measurement and various physics experiments. 2. Features Helmholtz coils offer a large volume of uniformity, an open and accessible working space, and simple operation. They can be configured to produce one-dimensional, two-dimensional, or three-dimensional combined magnetic fields, and can provide both AC and DC fields. The relationship between current and magnetic field strength exhibits excellent linearity. These coils are suitable for magnetic material research or testing experiments conducted by research institutes, universities, and enterprises. They find applications across multiple disciplines including materials science, electronics, biology, medicine, aerospace, chemistry, and applied physics. Primary uses include: Generating standard/reference magnetic fields. Cancelling and compensating the Earth's magnetic field. Simulating geomagnetic environments. Evaluating magnetic shielding effectiveness. Conducting electromagnetic interference (EMI) simulation tests. Calibrating Hall probes and various magnetometers. Researching biological magnetic fields and studying the magnetic properties of materials. 3.
