Electrostatics Apparatus and Machines

Charge generation, detection, attraction and repulsion each have dedicated apparatus. Check your syllabus topic before ordering, whether that's a generator, an electroscope or a friction rod kit.

Static electricity demonstrations work best in dry conditions. On humid days, charge leaks away faster, so plan demonstrations accordingly or allow extra time for charge to build.

An electrostatics kit bundles the core apparatus for a full lesson, while individual items like a friction rod kit or electroscope suit schools building up their equipment gradually.

A single demonstration set suits teacher-led lessons, but hands-on electrostatics practicals need enough friction rods and pith ball sets for every group to run the experiment themselves.

A typical electrostatics kit includes friction rods with cloths, pith balls on threads, and sometimes a small electroscope, giving you the core apparatus for a full lesson on charge, attraction and repulsion.

A moving belt inside the generator transfers charge onto the metal dome. As charge accumulates, it becomes strong enough to make hair or tissue paper stand up, or even produce a visible spark.

When a charged object touches the electroscope's plate, charge spreads down to the thin gold leaves. Since both leaves carry the same charge, they repel each other and visibly separate.

Moisture in humid air helps static charge dissipate quickly, weakening the effect. Electrostatics demonstrations are more reliable and dramatic in dry conditions.

Yes. We regularly supply schools with class sets of friction rod kits and pith ball apparatus. Contact us for a quote on bulk quantities for a full classroom or department.
