United Scientific® Deluxe Current Balance Kit – Magnetic Field & Electric Current Force Demonstration Set

Explore the principles of electromagnetism and Lorentz force with the United Scientific® Deluxe Current Balance Kit. Designed for advanced physics classrooms and lab demonstrations, this high-precision kit includes a clear air-core solenoid and a sensitive current balance to visually demonstrate and measure the force exerted on a conductor carrying current in a magnetic field.

The transparent acrylic solenoid accommodates the current balance arm and offers multiple tap points for accessing up to 500 turns of wire. As current flows through the balance and solenoid, the interaction generates a deflection, which can be measured by restoring balance with small masses. It’s an effective hands-on way to study magnetic force, current direction, and field strength. Includes an activity guide for structured learning.

Perfect for physics educators, STEM labs, and advanced science experiments.
