Conductor Ball

Product Code : SCL-EI-10683

The Conductor Ball 30 mm is a physics laboratory electrostatics accessory manufactured and exported by Lab Glassware Manufacturer, Ambala, Haryana, India, a manufacturer and exporter of laboratory glassware, scientific instruments, and STEM teaching apparatus since 1982. It is a conductive spherical accessory used for demonstrating electrostatics, charge transfer, charge distribution, and induction, and is supplied to schools, colleges, and STEM laboratories across India and to export buyers in countries including South Korea, Japan, Taiwan, and Hong Kong, and across the East Asia region.

Quick answer: The Conductor Ball 30 mm is a simple, reusable conducting sphere used to make electrostatic charge visible and repeatable in the classroom: students can charge it by contact or by induction, then use it with an electroscope, pith ball, or another Lab Glassware Manufacturer electrostatics accessory to observe how charge distributes and transfers. Exact conductive material, mounting stem, and certification status vary by unit — check the specific listing before ordering.

Technical Specifications

Applications / Uses

• Demonstrating how charge distributes over a conducting sphere
• Showing charging by contact and charging by induction
• Using with an electroscope to detect transferred charge
• Comparing conductor and insulator behaviour in physics practicals
• Supporting school demonstrations on static electricity and electrostatic force
• Building complete classroom electrostatics experiment sets with other electronic instruments

How to Use the Conductor Ball 30 mm

1. Place the conductor ball on a clean, dry, insulated support if the support is supplied or available.
2. Discharge the ball before starting by touching it with an approved grounding lead or as instructed by the teacher.
3. Bring a charged rod near the ball to demonstrate electrostatic induction, or touch the ball with a charged object to demonstrate conduction.
4. Use a pith ball, electroscope, or charge detector to observe the presence and movement of charge.
5. Repeat the activity with different charged materials and record the observations.

Safety note: Use this conductor ball only for low-energy classroom electrostatics. Do not connect it to mains electricity or high-voltage equipment unless the apparatus is specifically rated and supervised by a qualified instructor.

Care & Maintenance

• Wipe the ball with a clean, dry, lint-free cloth after use.
• Store it in a dry cabinet to reduce oxidation, dust, and moisture effects.
• Avoid dropping or denting the spherical surface, as deformation can affect demonstration quality.
• Keep it away from corrosive chemicals and wet laboratory areas.

Building a Complete Electrostatics Bench Set

A Conductor Ball is most useful as one accessory in a small electrostatics teaching set, since it needs a charging source and benefits from an instrument that can show or measure the result. Schools can pair it with an Electrostatic Pendulum for a second, independently visible demonstration of the same charge, an Electrostatics Starter Kit for a broader set of induction and charge experiments, and a Coulombmeter to move from a qualitative demonstration to a measured numeric value for the charge involved.
