Experiment Ei-10
Field of a Solenoid
Description: A
solenoid is made of heavy conducting wire, placed in a transparent box, and put
onto a projector so that its axis is parallel to the projector's glass plane.
Iron fillings are sprinkled somewhat evenly throughout the box and the box is
closed. When a current is passed through the solenoid, the filings align themselves
in the electric field.
Experimental
setup: solenoid in a transparent box with iron filings and an applied current.
The field lines are projected for the class using the projector.
Iron
filings showing field lines (black dashed lines added to make it easier to see
effect).
Materials: heavy
wire solenoid, transparent box, power supply connectors, DC power supply,
iron filings, projector
