Objective

Show the shape of the magnetic field lines around current-carrying solenoid.

Assembly Instructions

Instructions
The solenoid form is mounted on a plastic base for projection on the overhead. Connect the form through a switch to the LVDC power supply and set the current for about 20 amps. Place the petri dish under the form and sprinkle on iron filings; they will align themselves with the field lines. It may be helpful to tap the plate lightly to give the filings a chance to move. After the particles are aligned, open the switch so that the form does not overheat. The same demonstration may also be performed with a double-solenoid form. Note that a straight wire and a toroid are also available.
