Ampere’s Law Accessory - EM-6720
Students can verify Ampere’s Law experimentally by graphing the magnetic field strength that is tangent to the path taken along a closed path that encloses a current source.
Product Summary
Students can verify Ampere’s Law experimentally by graphing the magnetic field strength that is tangent to the path taken along a closed path that encloses a current source.
The magnetic field strength is measured with a Wireless Magnetic Field Sensor which rides on a Rotary Motion Sensor. The student pushes the Rotary Motion Sensor, which rolls on its wheel, along a closed path.
If you traverse a path that does not enclose any current source, the area under the curve is zero. The magnetic field of the Earth or any nearby source is measured but they will cancel out in a closed loop that encloses no current.
