Inducción electrostática con electroscopio

Principle

The students apply their knowledge of electrostatic induction to the electroscope. They recognize why a pointer deflection can appear even as a charged object approaches the electroscope. They can explain the series of events in the electroscope.

Benefits

  • Quick and easy ...

Conservación del momento en colisiones inelásticas con rielde demostración y cronómetro 4-4

Principle

An impulse acting on an object is defined as the change in momentum caused by a force Fover a short period of time t. The momentum p is defined as the product of force and time. It is conserved, provided that there is no friction and that the collision is elastic. This ...

Péndulo de Waltenhofen

Principle

When a massive body made of conductive material moves through a magnetic field, eddy currents are induced. According to Lenz's law, the body is then subjected to a force which is opposed to the cause of the eddy currents, i.e. the motion of the pendulum. The braking action increases ...

Movimiento rotatorio por flujo turbulento - principio del medidor de corriente alterna

Principle

A metal disc rotates on a bearing-mounted shaft in the presence to two out-of-phase alternating magnetic fields. Eddy currents are induced in the disc and forces are imparted onto this current-carrying conductor. Out-of-phase alternating fields also cause the rotational movement ...

Generación de voltaje alterno y rectificación

Principle

An alternating voltage is induced in a coil in the (alternating) field of a periodically moving magnet. The characteristic of a diode to allow electric current only to pass in one direction is used to rectify the induced alternating voltage. A capacitor that is connected in parallel ...

Conmutador bimetálico

Principle

A bi-metal strip comprises two metal strips which are laminated together and have different thermal expansion coefficients. When warmed the strip flexes toward the side with the lower expansion coefficient. In so doing, it can act as a switch in the electric circuit.

Conversión de la energía eléctrica en energía mecánica

Principle

A motor that raises a load, i.e. converts electrical energy into mechanical energy, is a familiar everyday sight. The special feature of this set-up is that it can be used to generate electrical energy again directly from the descending weight. That electrical energy illuminates a ...

Autoinducción al encender el circuito

Principle

A coil is located in a DC circuit. When the circuit is closed, the magnetic field of the coil builds up and generates a self-induction voltage which counteracts the increase.  An incandescent lamp in the circuit lights up only gradually.

Resistencia de alambres en relación a su longitud y sección transversal

Principle

The resistance of a short thick wire is different to that of a long thin one.

Benefits

  • Flexible experimenting thanks to wireless data transmission
  • No additional cable connections between the building blocks needed - clear arranged and quick setup
  • Contact safety due to ...
