Lb 4.2

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 ...

Atténuation d'un pendule par courants de Foucault (Pendule de Waltenhofen)

Principe de l'expérience

Quand un corps conducteur massif se déplace à travers un champ magnétique, des courants de Foucault sont induits. Selon la loi de Lenz (règle de la main droite), le corps est ensuite soumis à une force qui s'oppose à ...

Rotary motion by turbulent flow - principle of the alternating current meter

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 ...

Eep 10.1

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.
