Conservation of momentum in elastic collisions with the demonstration track and the timer 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 ...

Waltenhofen Pendulum

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 ...

Rotary motion by turbulent flow - principle of the

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 ...

Self-induction when switching a circuit on

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.
