Ruhmkorff Induction Coil
Model Number: MTE-015
Ruhmkorff Induction Coil is a practical electromagnetic apparatus used to demonstrate induction, voltage transformation and electrical spark discharge in physics laboratories. It operates with a 6–8 V DC input and uses insulated copper-wire windings to generate high-voltage pulses through electromagnetic action. The apparatus includes an interrupter mechanism and a pair of pointed electrodes with insulated handles for observing and adjusting the spark gap. Available spark-length options make it suitable for different classroom demonstrations and practical experiments. Micro Technologies supplies this laboratory induction coil for schools, colleges, universities, research laboratories and educational institutions requiring reliable physics experiment equipment for electromagnetic studies.
Product Specification
The Ruhmkorff Induction Coil is a classic physics laboratory apparatus used to demonstrate electromagnetic induction and the generation of high-voltage electrical pulses from a low-voltage DC supply. It provides a straightforward way for students to observe the practical effects of changing magnetic fields and understand the relationship between current, magnetic flux and induced voltage.
The unit operates from a 6–8 V DC supply through 4 mm socket terminals. Its coil assembly uses insulated copper wire, with the winding supported by an insulating paraffin-wax treatment. An integrated interrupter periodically interrupts the primary current, producing the changing magnetic field required for induction in the secondary winding.
A pair of pointed electrodes with insulated handles is supplied with the apparatus. These electrodes allow the spark gap to be adjusted according to the experimental requirement. Different versions are available with approximate spark lengths of 10 mm, 25 mm, 50 mm, 75 mm and 100 mm.
The Ruhmkorff Induction Coil can be used for demonstrations involving electromagnetic induction, self-induction, magnetic fields, induced voltage, electrical discharge and basic high-voltage phenomena. It is particularly useful in practical physics classes where students benefit from seeing the effect of electromagnetic principles rather than relying solely on theoretical explanations.
The compact arrangement makes the equipment convenient for tabletop laboratory demonstrations. The wooden base provides a stable platform for the coil and associated components, while the insulated electrode handles improve practical handling during demonstrations. Proper operating procedures should always be followed because the secondary circuit produces high voltage.
Micro Technologies supplies this Ruhmkorff Induction Coil for educational and laboratory applications, including institutional procurement, replacement requirements and bulk laboratory setups. Its reusable construction makes it a valuable addition to physics laboratory equipment inventories where electromagnetic experiments are conducted regularly.
For dependable performance, the coil should be protected from moisture, excessive dust and mechanical impact. The electrodes, terminals and interrupter should also be inspected periodically to maintain proper working condition.
