"PHYWE"

Supplier: PHYWE

Made of cast iron with coating of reinforced plastic. Intended for cylindrical stand rods with a diameter of 4 to 15 mm or square stand rods with a cross section of 4×4 to 12×12 mm. A 28×9 mm socket in the bottom of the foot is suitable for ordinary wooden scales, which is why the foot can be used to advantage in, for example, optical experiments.

Supplier: PHYWE

Intended for interconnection of cylindrical rods 4 to 18 mm and/or square rods with a cross section of 4×4 to 12×12 mm. The sleeve can also be used for clamping plates with ∼2 to 14 mm thickness.

Describes 70 different experiments, on 288 pages, that can be performed in the areas.

Supplier: PHYWE

Newton double-scale dynamometers and overload protection. Zero adjustment up to 19 mm with adjusting screw for compensation of different loads eg. when tilted depending on the test setup. Skull length 12 cm for 0,1 mN and 11 cm for the other dynamometers in this series. Measuring accuracy ±0,5% of the measured value. Dynamometer cover length 18 cm.

Supplier: PHYWE

Coil springs made of spring steel. With stirrups at both ends. Suitable for Hook's team and swing attempts.

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 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').

Educational Materials, Electricity/Magnetism, Application: Physics, Measurement insert for pressure For measurement and demonstration of pressure. Scale graded in bar. Comes with measuring probe and cable

Supplier: PHYWE

PHYWES well-known demonstration multimeter ADM 2 has now been supplemented with the new, slightly smaller but still powerful ADM 1. ADM 1 is a passive, user-friendly instrument for measuring current and voltage (AC/DC).

Supplier: PHYWE

For demonstration of electric fields between electrodes of different shapes. The electrodes have been applied in thin conductive layers on plexiglass plates and the field line images appear in groats placed in a cuvette with 1 to 2 mm castor oil (the cuvette is placed on the plexiglass plate). The cuvette has an annular electrode in the outer jacket and a 4 mm connection sleeve. The cleaning is easy when electrodes resp. plexiglass plate never comes into contact with the oil. Suitable voltage source: High voltage generator 0 to 25 kV or Van de Graff generator.

Supplier: PHYWE

Used to detect thermal radiation, visible light and ultraviolet light. The sensitivity is wavelength dependent in the range 150 nm-15 µm. The output voltage is closely proportional to the incident radiant energy. Suitable for measuring small temperature differences. Quick stabilization, 2-3 p. Consists of 16 series-connected thermocouples placed in a conical reflector. The elements are protected by a high-gloss metal cylinder, which is fitted with a removable protective glass at the front. Suitable for use with, for example, microvolt amplifiers 765-1293 in conjunction with demonstration instruments 765-1247 or for connection to Phywe's large analog or digital demonstration multimeters. Comes with protective tube and gap.

Supplier: PHYWE

Ice cream sphere filled with noble gas of low pressure. The tube's two cylindrical necks are protected by plastic sleeves and are designed to fit in Helmholtz coils 765-1207. The tube is used to show how an electron beam is deflected in a magnetic field. If the tube is in a homogeneous magnetic field with sufficient strength, the electron beam becomes circular. The tube is equipped with an internal measuring scale with fluorescent markings at distances of 4, 6, 8 and 10 cm (2r) from the cathode. The tube is well suited for determining the charge-mass ratio of the electron with great accuracy.

Supplier: PHYWE

Same as 765-1149 but without painting. 50 components incl. Manual.

Supplier: PHYWE

Precision capacitor for electrostatic tests e.g. examination of the relationship between charge, voltage and capacitance. Measurement of the dielectric constant and the electrostatic induction constant. The permanently mounted plate is well insulated while the movable plate is mounted directly in the stand. The distance between the capacitor plates can be adjusted with an accuracy of 0.1 mm. Distance between plates 0 to 70 mm.

Supplier: PHYWE

TESS OE3 contains 19 components. With TESS OE3 as a complement to TESS OE1 and OE2, another 30 experiments can be performed in the field of wave optics. Delivered in a plywood box.
