Fuerzas entre la bobina primaria y secundaria (anillo de Thomson)

Principle

This experiment demonstrates the force on a closed conductor in which current is being induced. Using DC in the primary coil, there is a pulse as the power is turned on and the coil is forced away. Using AC, the coil hovers over the primary coil.

Conducción de alta tensión

Principle

When electrical energy is transmitted over long distances, it is unavoidable that there will be losses due to resistance in the lines. Using transformer stations and high-voltage transmission lines can drastically reduce such losses. To model such lines, two wires of 1 m in length and ...

Demostración del efecto de Barkhausen

When a sample of iron or nickel is gradually magnetised, the stronger magnetism is not assumed throughout the volume of the metal all at once. Specific areas (Weiss domains) spontaneously change alignments at various times. Every time an alignment changes, a voltage is induced, which can be ...

Fluorescencia de resonancia de sodio

Principle

Resonance fluorescence is demonstrated by illuminating a sodium vapour with white visible light. The emitted light is spectrally analyzed and shows the emission spectrum of sodium. Therefore the same atomic levels are involved in both absorption and emission.

Combinación sojetiva de colores

Principle

If a circular disc separated into various differently coloured sectors is rotated by a motor so fast that the eye can no longer distinguish the colours, a mixed colour is then perceived. By varying the composition and size of the sectors, it is possible to give the impression of any ...

Comparación de diferentes tipos de colectores solares

Principle

A collector test field can be used to investigate the temperature response of four differently designed solar collectors. It also demonstrates the effect of the absorber's colour, of heat insulation and covering of the glass. Measurements are made simultaneously and ...

Medición de longitudes

Principle

The students should measure length, diameter, and hole depth of various objects with a measuring tape and/or vernier caliper as possible. In doing this they should choose and use the more suitable measuring device. The results should be entered in the table as a numerical value ...

Medición de tiempos

Principle

The student should count the oscillations of a pendulum while timing them with the aid of a stopwatch. To determine the dependence of the oscillation period on  the length of the pendulum is shortened by 50% in the second part of the experiment.

The oscillation period of ...

Determinación de la masa de sólidos y líquidos

Principle

1. The students should determine the mass of solid bodies with the aid of a balance. 

2. The measurement of the mass of liquids can only be performed using a container. The students should determine the mass from the difference of two measurements.

Tasks

How does ...

Determinación del volumen de cuerpos regulares e irregulares

Principle

The students should determine the volume of 3 solid bodies. In doing this they should know that the cubic meter (m3) is the unit of volume and also that the term liter (l) is very common.

  1. On immersion of a solid body in a graduated cylinder, the difference of the ...

Determinación de la densidad de sólidos

Principle

In the previous experiments on determination of mass and volume (ME 1.3 and ME 1.4), the students have learned that both metal columns have the same volume but different masses. They know that the two objects consist of iron and aluminium. Obviously, the two materials ...
