The Pioneers – Stewart and Gee
The Stewart & Gee Experiment was conducted by British physicists Harold Stewart and Albert Gee in the early 20th century. Their aim was to investigate how magnetic fields vary concerning distance and other parameters. They devised an ingenious setup to carry out their investigation.
Experimental Setup
The experimental setup was designed meticulously to ensure accurate and reliable results. It consisted of the following components:
3.1. Magnet
A strong magnet was used as the primary source of the magnetic field. The magnet’s dimensions and properties were carefully measured and accounted for in the subsequent analysis.
3.2. Magnetic Field Probe
To measure the magnetic field’s strength at various points, Stewart and Gee employed a magnetic field probe. This probe was carefully calibrated to ensure precise measurements.
3.3. Measuring Apparatus
The researchers used a measuring apparatus to record the magnetic field’s strength at different distances from the magnet. This apparatus was designed to be movable, allowing measurements at various distances.
Conducting the Experiment
The Stewart & Gee Experiment involved several steps to gather relevant data and draw meaningful conclusions. The procedure included the following stages:
4.1. Baseline Measurement
Before introducing any variables, the initial magnetic field strength was recorded at a specific distance from the magnet. This served as the baseline reference for further measurements.
4.2. Varying Distance
The researchers then moved the measuring apparatus away from the magnet and recorded the magnetic field’s strength at increasing distances. This step was crucial to understand how the magnetic field’s intensity changes with distance.
4.3. Introducing Barriers
In some variations of the experiment, barriers or materials with varying magnetic properties were introduced between the magnet and the measuring apparatus. This helped explore how obstacles and different materials affected the magnetic field.
Observations and Results
Upon conducting the Stewart & Gee Experiment, the researchers made several noteworthy observations and obtained significant results:
5.1. Inverse Square Law
The experiment’s findings aligned with the inverse square law for magnetic fields, indicating that the magnetic field strength decreases as the distance from the source increases. This was a groundbreaking confirmation of the existing theoretical framework.
5.2. Influence of Barriers
The experiment also revealed that the introduction of barriers and materials with varying magnetic properties affected the magnetic field distribution significantly. This highlighted the importance of considering the environment when dealing with magnetic fields.
Significance and Applications
The Stewart & Gee Experiment’s results hold immense significance in the world of magnetism and beyond. Some notable applications include:
6.1. Electromagnetic Technology
Understanding magnetic field variations is crucial for the development and optimization of electromagnetic technologies, including electric motors and generators.
