5h15.11: MAGNETIC FIELD - EME SET - STRAIGHT WIRE

PURPOSE: To visualize the magnetic field around a straight wire.

DESCRIPTION: The magnetic field around a straight wire can be visualized by sprinkling iron filings in the area around where the wire passes through a plastic sheet which is positioned on an overhead projector. Alternatively, small compasses ca n be arranged around the wire.

SUGGESTIONS: This is a portable version; a better choice in Physics classrooms is J5-16: MAGNETIC FIELD AROUND WIRE, LOOP, SOLENOID.

REFERENCES:

EQUIPMENT: EME magnetic field apparatus with battery electric current source on overhead projector.

SETUP TIME: None.
