Product Overview
Uniform Magnetic Field Generator for Physics & STEM Classrooms
The Helmholtz Coil Apparatus is a precision magnetic field generation system designed for physics classrooms, STEM labs, and advanced science instruction. Consisting of two identical circular solenoids spaced one radius apart, this apparatus produces a highly uniform magnetic field in the central region—ideal for quantitative experiments and demonstrations.
This classroom-ready Helmholtz coil for physics labs allows students to investigate magnetic fields, electromagnetic interactions, and the relationship between current and field strength using a controlled, repeatable setup.
