Aluminum Collecting Sphere EG-03
--- Instruction Manual ---
Thank you for purchasing the optional Aluminum Collecting Sphere for the electrostatic
generator. Read these instructions carefully and conduct experiments safely by following the
described procedure.

2. How to Use (examples)
Experimenting Electric Line of Force (Electric
Umbrella)
①Prepare thin moisture-resistant paper such as
pharmaceutical packaging paper. Cut out seven
strips, each approximately 2 mm wide and 50 mm
long.
②Attach one strip to the top of the sphere, and the
remainder to the side at uniform intervals.
③Place the sphere on the provided PVC plate (Photo
1).
④Referring to Photo 2, connect the output cables of
the electrostatic generator to the electrode
terminals of the PVC plate and the sphere,
respectively. The negative polarity is connected to

Specifications (materials and other details)
①Aluminum collecting sphere:
Consisting of two aluminum hemispheres,
each 2 mm thick and 50 mm in diameter,
which are pasted together.
②Base: Made of resin, including the post.
③Electrode terminal:
Consisting of one each M3 screw and nut.
Accessory: One polyvinyl chloride (PVC) plate, 1 mm thick.
* The materials and dimensions of the parts are subject to
change for improvement without prior notice.

the sphere in the photographs. Experiments yield
the same results if you reverse the polarity.
⑤Turn the handle of the electrostatic generator slowly. The paper strips are levitated
gradually until they float in the air as shown in Photo 3. The user can estimate the
direction of the electric lines of force (virtual lines) by noting the direction of the floating
strips.
The base and the post are made of acrylic resin. Do not wipe with alcohol or other solvents nor
allow them to spill over the acrylic parts. Prevent severe shocks such as fall to the housing.
(The housing will be cracked or split.)
