The whirl is placed on top of the Van de Graaff generator’s dome.It is placed on the supplied needle.

For demonstration of electromagnetism.

This electromagnetic coil becomes magnetic when a voltage of 4 – 6 V DC is applied, and an elongated square iron plate is included, which can be used to demonstrate when the coil is magnetic.

Holder for electrodes up to Ø 7.5 mm.

This instrument measures very small current and charge, and enables a range of fascinating experiments to be performed.

Compatible with 512525 and 513565.

Ball shooter for illustrating the principle of independent horizontal and vertical motion: The throwing motion can be seen as composed of free-fall and horizontal motion.The shooter fires one ball horizontally and the other is released in free-fall.

Used with electrometer 441030 or electroscope 441000 for demonstrating electrostatic induction.
