Electromagnetic Fields

Lab Summary

Use a magnetic field sensor measure the magnetic field strength of two coils with different radii and number of coil windings as the current flowing through the coils is varied and measured using a voltage current sensor.

Theory

Measure the electromagnetic field strength of two coils with different radii and number of coil windings as the current flowing through the coils is varied. Then use the magnetic field strength and current data to determine an experimental value for the permeability of free space.

Method

Students gain experience conducting the following procedures:

  • Using magnetic field and current sensors to measure the field strength versus current for two different solenoids with varying turns per unit length.
  • Plotting this relationship in a graph.
  • Using the acquired data to determine an experimental value for the permeability of free space.

Sensors / Equipment Used:

PASPORT Voltage-Current Sensor

(PS-2115)

Allows students to safely measure voltage and current simultaneously without overloading the sensor. For use with PASPORT Interfaces.

PASPORT Magnetic Field Sensor
