Two identical coils with a diameter of 400 mm (2R), 154 turns of winding each and mounted on separate sockets with connection contacts. Distance between coils 200 mm (R). The coils are held together by three detachable rails. Two of these have brackets for wire beam tubes 765-1206. The coils are used, for example, to provide a homogeneous magnetic field in the wire beam tube. Suitable voltage: 7 V DC (well smoothed) if the coils are connected in parallel and 14 V DC for series connection.

Supplier: GR NNA PLASTEMBALLAGE AB

Model experiments with practical examples of working methods in genetics. During the experiments, the students quickly make so many observations that their calculations of outcomes can be considered statistically reliable. The experimental kit contains four cans of tubes and colored beads for experiments in some of the different areas of genetics. Blue or brown eyes? Boy or girl? How many peas turn yellow? Trial description included.

Supplier: PHYWE

Equipment for demonstrating photoelectric power and determining Planck's constant. A photocell is equipped with filters that only transmit light of a certain wavelength. The photocell is illuminated with light from a Hg lamp. The potassium cathode then emits electrons that pass over to the unlit anode. Over time, a voltage arises that prevents new electrons from reaching the anode. The resulting voltage is measured with a measuring amplifier and a voltmeter. The measurement is repeated with filters for different wavelengths. Photocell and Hg lamp are equipped with magnets at the bottom for stable installation on the mounting plate. List of equipment.

This experiment shows how fast a vertical pendulum would swing, if it was placed on a foreign celestial body e.g. the moon or March. Phywe's variable g-pendulum can change the plane of oscillation from the vertical, a=0°, up to the horizontal plane, ie a=90°. When a=0°, g acts at full force. If the plane of oscillation is not parallel to the vertical, only g × cos a acts on the pendulum motion. A movement to the moon shows that gravity amounts to about 16.6% of the earth's, which in our pendulum on the earth, corresponds to an angle α=80.5°. The force of attraction in March amounts to 38% of the earth, which can be simulated in the g-pendulum by setting a= 69°.

With a few simple steps, the ballistic pendulum is quickly rebuilt into a throwing device with a variable/variable firing angle. The ballistic pendulum, a common method for determining the speed of a pistol bullet, is to push them into a sandbag. With the ballistic pendulum, a harmless variant of this experiment can be performed in the classroom.

The following experiments can be performed.

Supplier: CORNELSEN EXPERIMENTA

Insulated rod with 3 connection terminals for wire up to 2 mm and 4 mm contact sleeve.

Supplier: MOLLER THERM

Radiometer according to Crookés. Consists of a glass container on foot with low air pressure and needle-bearing spinner with four vertical mica discs. The discs are black on one side and shiny on the other. The discs thus absorb radiation differently. The higher temperature of the dark side means that the air molecules get greater kinetic energy in collision with the dark side of the discs than with their shiny side. The result is that the spinner starts to rotate.

Supplier: PHYWE

With a special addition, the analogue instrument can be turned into a digital instrument with simultaneous analogue display. In order to extend the measurement possibilities, there are also measurements for power and voltage amplification. The replaceable measuring areas are slid into a slot on the top of the instrument ('toaster principle').

Equipment for demonstration of the quantum properties of the electric charge, as well as to determine the elementary charge. The experiment is easy to perform and suitable for both laboratory and demonstration using the Videoflex camera (765-1000). With the equipment, the elemental charge can be determined in 3 ways: change of charge by means of an alpha radiator, falling and rising speed with constant capacitor voltage and free voltage and falling speed without electric field.
