Coil with 12 turns

Product Code : SCL-EI-10687

The Coil with 12 Turns is a fixed-winding physics laboratory coil used for demonstrating electromagnetism, magnetic field production, electromagnetic induction, and current-related effects in supervised school and college practicals.

Quick Answer: The Coil with 12 Turns is a 12-turn wound conductor connected to a suitable low-voltage classroom circuit to demonstrate magnetic field formation, induced current, and coil behaviour. It is typically compared against higher-turn coils such as the Coil with 400 Turns, or mounted with a core such as the U-Core with Yoke, to show how winding count and core material affect magnetic field strength and induction response.

Technical Specifications

Specification	Detail
Product Name	Coil with 12 Turns
Product Category	Physics Lab Equipment / Electromagnetism Demonstration Apparatus
Intended Users	Schools, colleges, physics teachers, laboratory technicians, STEM labs, and educational procurement teams

Check that the winding, insulation, terminals, and connectors are clean and undamaged.
Connect the coil only to a suitable low-voltage power source or measuring circuit as instructed by the teacher.
Place a magnetic compass, magnet, galvanometer, or sensor near the coil depending on the experiment.
Switch on the circuit briefly and observe the magnetic deflection, field effect, or induced current response.
Record the observations and disconnect the coil after completing the practical.

Safety note: Do not connect the Coil with 12 Turns directly to mains electricity. Use only the rated low-voltage supply, avoid overheating, and disconnect immediately if the coil becomes warm or damaged.

Care and Maintenance

Store the coil in a dry cabinet with other general lab equipment.
Do not bend, pull, or unwind the coil, as this can change its electrical and demonstration behaviour.
Keep terminals clean and free from corrosion for reliable circuit contact.
Use suitable safety protective wears when conducting broader electrical or laboratory demonstrations.

Comparing Coil Turn Counts for Electromagnetic Induction Lessons

The Coil with 12 Turns is best understood alongside other winding-and-core components in the same teaching progression. For lessons comparing how winding count changes magnetic field strength and induced current, pair it with the Coil with 400 Turns. To demonstrate how a ferromagnetic core concentrates the magnetic field produced by a coil, mount it on the U-Core with Yoke or the I-Core. Schools building a complete transformer and electromagnetic induction module often source all of these together with the Mains Coil with 600 Turns.
