The Ruhmkorff Coil by Scientifc Equipment is an educational physics laboratory apparatus designed to demonstrate electromagnetic induction, high-voltage generation, step-up induction, spark discharge, primary and secondary coil action, interrupter operation, magnetic flux change, and transformer principles. It is suitable for school physics laboratories, college science labs, STEM classrooms, electromagnetism lessons, teacher-led demonstrations, and supervised student practical activities.

This apparatus helps students observe how a low-voltage input can produce a higher-voltage output through rapid changes in current and magnetic field. It provides a practical way to introduce induction coils, spark gaps, electrical discharge, and historical electrical apparatus used in the study of electromagnetism.

Product Description

A Ruhmkorff Coil, also known as an induction coil, is used to produce high-voltage pulses from a low-voltage electrical source. It generally contains a primary coil, secondary coil, iron core, interrupter, capacitor or condenser arrangement, and output terminals. When the primary current is interrupted rapidly, the changing magnetic field induces a high voltage in the secondary coil.

The Scientifc Equipment Ruhmkorff Coil may include an induction coil assembly, primary and secondary winding, soft iron core, adjustable spark gap, interrupter mechanism, terminals, base board, connecting leads, activity sheet, and instruction guide depending on product configuration. It is designed for supervised educational and laboratory demonstration use only.
