Circular Coil One Turn

Product Code : SCL-EI-10703

This single-turn circular coil is used to demonstrate magnetic field production, electromagnetic induction, current effects, and circular-loop field behaviour in school and college physics laboratories.

Quick Answer: The Circular Coil, 1 Turn is a single-loop demonstration coil used with a low-voltage supply, magnet, or galvanometer to show basic magnetic field formation, apply the right-hand rule, and provide a simple reference point when comparing results against multi-turn coils such as the 5-turn or 12-turn versions.

The Coil, Circular, 1 Turn from Lab Glassware Manufacturer is designed for electricity and magnetism practicals where a single-turn loop is required. It is useful for showing the magnetic field produced by a circular conductor and for comparing 1-turn coil behaviour with coils having 5, 12, or more turns. This product belongs to the physics lab equipment category and is intended for supervised educational use.

Key Features

• Single-turn circular coil: Provides one defined loop for basic magnetic field and induction demonstrations.
• Useful for comparison work: Helps compare magnetic response against coils with higher turn counts.
• Supports field-direction teaching: Allows students to apply the right-hand rule to a circular current loop.
• Suitable for induction activities: Can be used with magnets and meters to observe induced current where compatible.
• Compatible with lab instruments: Works with suitable low-voltage supplies, galvanometers, sensors, and electronic instruments where rated.
• Reusable teaching component: Suitable for repeated physics practicals when handled and stored correctly.

What's Included in the Kit

• 1 × Coil, Circular, 1 Turn
• Terminal posts, leads, or connectors
• Mounting base, frame, or holder
• Instruction sheet or experiment guide

Applications / Uses

• Demonstrating magnetic field formation around a circular current loop.
• Showing field direction using the right-hand rule.
• Observing induced current when a magnet moves near or through the loop.
• Comparing 1-turn coil response with multi-turn coils.
• Using with compatible meters, magnets, low-voltage supplies, and general lab equipment.
• Supporting STEM lessons on electromagnetism, magnetic flux, and current effects.

How to Use the Coil, Circular, 1 Turn

• Place the circular coil on a dry, stable laboratory bench or compatible support.
• Check the loop, insulation, terminals, and connectors for visible damage.
• Connect the coil only to an approved low-voltage supply or measuring circuit.
• Place a compass, magnet, galvanometer, or magnetic field sensor near the coil as required.
• Switch on the circuit briefly or move a magnet through the loop to observe the response.
• Record the observation and disconnect the coil after completing the practical.

Safety note: Do not connect the Circular Coil, 1 Turn directly to mains electricity. Use only the confirmed low-voltage rating, avoid overheating, and use suitable safety protective wears during broader electrical demonstrations.

Care & Maintenance

• Store the coil in a dry cabinet after use.
• Do not bend, pull, reshape, or overload the circular loop.
• Keep terminals clean and free from corrosion for reliable electrical contact.
• Replace the coil if the loop, insulation, or connectors become damaged.

Comparing Coils Across Turn Counts

The 1-turn circular coil gives students the simplest possible reference loop before moving to multi-turn windings. For side-by-side comparison of how turn count affects magnetic field strength and induced response, it is commonly used alongside the Coil with 5 Turns, the Coil with 12 Turns, and the Coil with 400 Turns, letting a class build a complete progression from a single loop to a dense multi-turn winding using the same demonstration method. Confirm terminal and core compatibility with Lab Glassware Manufacturer if these coils are intended to be used together.
