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 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 |

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 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 |
