Primary and Secondary Coils
Product Code : EL-PLE-13166
Eduscope India is a leading Primary and Secondary Coils
Quick Answer: Primary and Secondary Coils is a refined electromagnetic induction apparatus with a 175-turn primary coil and a switchable 500/1000/1500-turn secondary coil around a movable plated iron core.
This set is a refined version of the classic apparatus used to demonstrate electromagnetic induction, the phenomenon first described by Michael Faraday in 1831. It is designed for hands-on physics instruction and is part of EduScope India's electronic lab instruments India range under Physics Lab Equipment, giving students a direct way to observe how a changing magnetic field induces current in a nearby coil. Both coils are wound on robust molded formers fitted with shielded banana jacks for secure, reliable connections during experiments. A plated iron core, fitted with a molded handle, allows students to position it accurately within the coils, making it easy to see how the core's position affects the induced current. The primary coil is wound with 175 turns of 18 AWG insulated copper wire, while the secondary coil offers three available windings of 500, 1000, and 1500 turns of 26 AWG insulated copper wire. Moving the iron core in and out of the coils, or switching between the secondary windings, lets students vary the induced EMF and directly observe how turns ratio affects electromagnetic induction.

It is part of EduScope India's Physics Lab Equipment range. To measure the current and voltage induced during these experiments, pair this set with EduScope India's Multimeter, Digital. For a further look at electromagnetic induction in practice, see the Hand Held Generator, a hand-cranked 6V DC generator built on the same underlying principle.
