Coupled Pendulum Set (0740)
Simple to set up and highly effective, the coupled pendulums transfer energy one to the other thanks to a thin string that couples them. This system allows teachers to introduce the normal modes of oscillation. The resultant motion corresponds to the composition of two oscillations: the centre of mass motion and the relative motion of the pendulums. COMPONENTS : • Threatened rod (2x) • Sphere with Hook (2x) • Polyester inelastic Cord. LAWS & PRINCIPLES INVETIGATED : • Pendulums • Energy transfer • Harmonic motion • Couplement • Resonance

Eddy Current Set (0741)
An eddy current is reproduced by using a “C” shaped magnet affixed to the track and then pass once of the kits screens through it. COMPONENTS : • Aluminium flag with slits • Aluminium flag without slits (1 mm) • Aluminium flag without slits (3 mm) • Magnetic poles “C” shaped • Metallic flag for motion sensor • Support for Magnet. Eddy current (also known as Foucault current) is a phenomenon caused by a moving magnetic field
intersecting a conductor or vice-versa. The relative motion causes a circulating flow of electrons, or currents, within the conductor. With this kit, students can easily study “electromagnetic brakes” (also called eddy current brakes), to retard motion or cause deceleration in a moving system. This type of brake converts kinetic energy to heat without contact between the moving parts. Heat is generated in the screen as a direct result of the Electrical resistance of the material and the current flow induced in it; this heat represents the kinetic energy being absorbed, and it’s analogous to heat generation in a friction brake.

Cart without Plunger (0744)
SPECIFICATIONS : Size: 14 x 7 x 4 cm – Weight: approx. 450 g. Ideal for all dynamics experiments, the Cart is an ideal companion for the Plunger Cart. Designed to be robust yet almost friction Free, designed so that it will withstand the rigours of any school laboratory. Manufactured from solid aluminium, we have used a special low friction wheel system. This system gives almost friction free movement and results which are accurate and repeatable time and time again. One side of the cart is fitted with Velcro™ strips, which are ideal for inelastic collisions, and on the other side, a pair of powerful neodymium magnets, which are ideal for elastic collisions.

Cart with Plunger (0745)
Specifications : Size: 14 x 7 x 4 cm – Weight: approx. 450 g. The cart includes a spring loaded plunger mechanism that can be released to provide an Immediate impulse to set another cart in motion and to provide
an initial impulse velocity. The plunger has two settings to allow a lesser or greater impulse depending on the mass of the adjacent cart. The other side of the cart contains two strips of Velcro™ and a pair of powerful neodymium magnets, which are designed for alternate elastic and inelastic collisions.
