Description: Interactive flash animation to study the parameters that influence the magnetic field in solenoid: Current? Length? Number of turns? Number of turns per meter?
Solenoid: type of electromagnet, the purpose of which is to generate a controlled magnetic field through a coil wound into a tightly packed helix. It produce a uniform magnetic field in a volume of space when an electric current is passed through it.
It's a coil whose length is substantially greater than its diameter.
