Experiments on Electricity and Magnetism 
Aluminium ring
Arago schijf en wet van Lenz
Building an Electromagnet An electromagnet is a device that uses an electric current to generate a magnetic field. It is generally made by coiling electrical wire around a core of iron or steel. Nickel and cobalt may also be used, ...

Crystal Radios-Building instructions for a crystal radio loud speaker
CRYSTAL SET RADIO Make a working portable AM radio without batteries Crystal Radio with Loop Antenna, Make a working portable AM radio without batteries. The shortwave bands provide entertainment and news for millions (perhaps billions) of people around the world. One BBC estimate I heard claimed that 100 million short wave radios sets are in use around the world! Outlined below are plans to make a shortwave crystal set radio that (with a good antenna and earth connection) is capable of receiving stations from around the world

Force between Two Magnets as a Function of Distance You can use a scale with a digital readout to measure the force between two magnets as a function of distance. A plot reveals that the force does not decrease as the inverse square of the distance
Hi-fidelity Homemade speaker
How to Build Modern Versions of Early Speaking Telegraphs
How do I make an electromagnet? All you need to do is wrap some insulated copper wire around an iron core. If you attach a battery to the wire, an electric current will begin to flow and the iron core will become magnetized, ...

Magnetic field and magnetic lines of force pdf file
Magnetic Oscillators One end of a magnet can be suspended in the air by repulsion from another magnet. push the suspended magnet gently down and it will oscillate for a long time. Suspend several magnets and they will interact magnetically
Magnet launching This little experiment shows a fundamental connection between electricity and magnetism in a very instructive way, In this experiment, a capacitor is charged from a power supply. The capacitor then is discharged through a very primitive coil. This induces a magnetic field for a short time. This magnetic field is strong enough to launch a small neodymium magnet
