J5-11. Magnetic Field - Eme Set - Straight Wire
Purpose
To visualize the magnetic field around a straight wire.
Suggestions
This is a portable version; a better choice in Physics classrooms is J5-16: MAGNETIC FIELD AROUND◙WIRE, LOOP, SOLENOID.◙

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 can be◙arranged around the wire.◙
