Primary and Secondary Coil

The Primary and Secondary Coil is a straightforward laboratory apparatus for demonstrating the principle of electromagnetic induction and helping students understand the basic operation of a transformer. It provides separate windings with different numbers of turns, allowing practical investigation of how changes in magnetic flux can induce voltage in a nearby coil.

The apparatus consists of a primary coil and a secondary coil mounted separately on durable plastic spools. Each coil is provided with two binding posts, giving users convenient connection points for compatible laboratory circuits, measuring instruments or power sources. The clear separation between the windings also makes the relationship between primary and secondary circuits easier to understand during classroom demonstrations.

The primary winding incorporates approximately 480 turns, while the secondary winding contains approximately 3800 turns. This difference in winding ratio provides a useful setup for demonstrating the effect of coil turns on induced voltage. Students can observe and discuss transformer action, magnetic coupling and electromagnetic induction using suitable laboratory instruments.

A soft iron core can be passed through the secondary coil for induction experiments. The removable core allows instructors to demonstrate how the presence of a ferromagnetic material affects the magnetic path between the coils. This makes the apparatus useful for experiments involving magnetic flux concentration, mutual induction and transformer principles.

The unit can be used alongside a suitable galvanometer, power supply, measuring instrument or other compatible physics laboratory equipment. Galvanometer, bar magnets and external accessories are not included unless specifically mentioned in the quotation.

Its simple construction makes the apparatus particularly useful for practical teaching because students can clearly identify the primary winding, secondary winding, connection terminals and magnetic core. It can support laboratory exercises in electromagnetism, electrical science and introductory transformer theory.

Micro Technologies supplies this Primary and Secondary Coil for educational laboratories, institutional setups and physics experiment requirements. The reusable construction and uncomplicated connection arrangement make it suitable for repeated practical sessions when handled and stored correctly.
