Product Overview
This comprehensive electrostatics demonstration set is designed to showcase key electrostatic concepts with high precision and clarity. Ideal for use in classrooms and labs, this set includes various essential tools for illustrating electrostatic charges, induction, and conduction. Each item is carefully chosen to demonstrate electrostatic principles in an engaging and visually informative manner.
Electroscopes, Large Needle, Set of 2
These rugged electroscopes feature ultra-sensitive aluminum needles (150 mm long) that pivot on an axle. The metal support rod is insulated with a plastic sleeve, reducing unwanted deflections from charges on the container. The electroscope’s metal case helps eliminate deflections caused by surrounding glass or plastic. Both the front and rear glass windows, 170 mm in diameter, provide excellent visibility. The transparent front window and the frosted back with a printed scale allow for easy measurement of deflection angles.
Friction Rods, Assorted Materials, Set of 7
This set helps students understand the triboelectric series and methods of charging by friction, induction, and conduction. It includes rods made from seven different materials: Nylon, PVC, Glass, Polystyrene, Acrylic, Ebonite, and Polyethylene. Each rod measures 10-12 mm in diameter and 150-170 mm in length.
Friction Pad, Pure Wool
This pure wool pad is used in conjunction with the electrostatic friction rods for charge generation. It measures approximately 250 mm x 240 mm. The color may vary, as bulk wool rolls are selected based on fabric performance.
Friction Pad, Pure Silk
A pure silk pad for use with the electrostatic friction rods, helping to generate charge. Dimensions: approximately 250 mm x 240 mm. The color may vary, depending on the fabric performance.
Electrophorus
This tool produces electrostatic charge by induction. The electrophorus includes a 15 cm brass disc with an insulating handle and a 4 mm plug, mounted on a 15 cm square plastic plate. Complete with instructions for use.
Sphere Conductor
A conductive sphere used to store charge and investigate electric potential. Mounted on an insulated stand with a wide, stable base. It has a wire lead with a spade connector that can be connected to a power supply or electroscope for experiments. The sphere is 95 mm in diameter, with a total height of 200 mm, including the base and stand rod.
Cylinder Conductor, Hollow, 2 Half-Cylinders
This cylinder conductor is ideal for induction experiments and studying the charge distribution on a hollow conductor. The two half-cylinders can be charged by induction, and the charge distribution can be tested by separating them and using an electroscope. Each half-cylinder is 60 mm in diameter, and the combined length is 160 mm, with a total height of 175 mm, including the base and rod.
Leyden Jar, Dissectible
Used to store static electricity and demonstrate capacitance principles. The plastic jar features a removable metal insert and outer shell, showing that charge resides on the surface of the plastic. The inner metal vessel has a hook-shaped rod with a metal sphere for charging. Even after disassembly, the Leyden jar retains its charge, making it a great demonstration of capacitance.
Proof Plane
A tool for sampling charge density on a charged conductor or transferring small charges between objects. The steel ball (14 mm in diameter) is mounted on a 100-mm insulating plexiglass handle, making it easy to measure charge densities and transfer charges.
Discharger
Used for insulated charge transfer between electroscopes. The discharger has an insulating plexiglass handle (135 mm long) and a steel wire (2 mm diameter, 260 mm long), making it ideal for safe charge transfer experiments.
This Electrostatics Demo Set offers everything needed to perform various electrostatic experiments, providing both hands-on learning and clear demonstrations of electrostatic principles in action.
