J5-12: MAGNETIC FIELD - EME SET - TWO-TURN HELIX

PURPOSE: To visualize the magnetic field around a two-turn helix.

DESCRIPTION: The magnetic field around a two-turn helix can be visualized by sprinkling iron filings in the area around where the helix passes through a plastic sheet which is positioned on an overhead projector. Alternatively, small compasses can be arranged within and around the helix.

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

REFERENCES: (PIRA 5H15.10)

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

SETUP TIME: None.
