Heated glass - electric conductor - physics experiment
http://www.fizik.si Led diodes are connected to batteries and to a glass rod. There is a gap between two wires on the glass rod, so electric current can't run through the circuit. When the glass rod is heated, it starts to conduct electric current. Led diodes light up. This is physics experiment f...

Electrolysis science experiment
www.fizik.si Copper (II) sulphate solution can be electrolysed using inert steel electrodes. During electrolysis, the cathode is coated with a layer of reddish-brown solid copper. The blue colour of the solution fades gradually as more copper is deposited. The resulting electrolyte also becomes incr...

http://www.fizik.si Flames are ionized gases and in some cases plasmas. The fact of being plasma or not, depends on the flame temperature and the burning material. A negatively charged baloons attracts positive ions in the lighter flame. The consequence of this is that the electric force between bal...

Diamagnetic levitation- Science experiment
http://www.fizik.si Diamagnetism is a property of all matter. That means that all substances responds to the presence of an external magnetic field with a repelling force. This force is very weak and it is described by Lenz's law. For the experiment we used pyrolytic carbon. Pyrolytic carbon respond...

Magnet trapped in the magnetic field - Science experiment
http://www.fizik.si The principle is that two similar poles repel and that two opposite poles attract, with forces that are stronger when the poles are closer. There are four magnetic forces on the small magnet on aluminum rod: on its north pole, repulsion from the base's north and attraction from t...

Heating effect of electric current - Science experiment
http://www.fizik.si NiTi (nickel titanium alloy) has two solid-state phases. Materials made of NiTi display an astonishing, counterintuitive property: while in their low-temperature phase they can be easily distorted into a different shape and upon warming into the high-temperature phase, the sample...

Magnetic properties - Diamagnetism - Science experiment
www.fizik.si Diamagnetism is a property of all materials and opposes applied magnetic fields, but is very weak. The orbital motion of electrons creates tiny atomic current loops, which produce magnetic fields. When an external magnetic field is applied to a material, these current loops will tend t...
