Light the fluorescent bulb using a plasma ball!

Materials: Plasma ball Fluorescent light bulb (any type) Procedure: Place the fluorescent bulb close to the plasma ball and watch it light up!!! Explanation: A plasma ball is a sealed glass containing low-pressure noble gases. A high voltage electrode sits in the center of the ball, connected to the power source. When the ball is…

Plasma ball

Materials: Procedure: Touch the plasma ball with your fingers and watch the plasma filaments. Explanation: A plasma ball is a sealed glass containing low-pressure noble gases. A high voltage electrode sits in the center of the ball, connected to the power source. When the ball is turned on, electrical current ionizes the gas in the…

Build a simple Electric Generator

Generators are the devices that convert kinetic energy into electricity. The operation of the generators is based on the induction phenomenon, according to which, if a magnetic field moves close to a conductor an electric current will flow in the conductor. Materials: 2 rubber ringstest tubeLED lightpowerful magnetscopper wire Procedure: Place the magnet and the…

Make a lemon battery

A battery is a device that stores chemical energy and converts it to electrical energy through chemical reactions. Materials: Four lemonsFour zinc nailsFour copper coinsFive crocodile wires and led Procedure: Place the coins and the nails on each of the four lemons as shown in the top images. Connect the nail on one lemon to the…

Build a Simple Electromagnet

An electromagnet is the magnet in which the magnetic field is produced by an electric current. Electromagnet consists of a coil wrapped with a wire. The current through the wire turns the coil into a magnet. Materials: 30 cm copper wireA long nailBattery 4.5 VoltPaperclips Procedure: Wrap the wire several times around the nail. Scrape the…

Build a simple electric motor

Electric motors are the devices that convert electrical energy into mechanical energy. Materials: Battery 1.5Volt2 circular magnetsInsulated copper wire Procedure: Place the two magnets on the negative pole of the battery. Shape the wire as it is shown in the image and place it on the positive pole of the battery. The two ends of the…
