Magnetic Field

Summary

This lab facilitates magnetic field experiments with a steady current in a straight conductor, whose intensity can be adjusted. A movable Hall sensor measures the field's magnitude at various distances. In this version of the lab students manually record the data.

 

Versions of the lab

In this version of the lab, graphs are not included and data download by the student is not permitted. Instead, the student must collect the data from the sensor readings and the distance to the conductor, similar to a traditional practical experiment. This allows them to construct their own graphs and create custom spreadsheets for data analysis and conclusion drawing.

There is an alternative version of the lab (Magnetic Field with Graph) in which a graph is provided at the end of each experiment and students are allowed to download the data onto a spreadsheet. This version may be especially useful for those students who prefer more direct access to the data collected during the experiment.

 

Magnetic Field

Moving charged particles have the ability to create a magnetic field around them, which can interact with other moving charged particles. In this context, a conductor through which an electric current flows generates a magnetic field in its surroundings. This physical phenomenon is fundamental in numerous technological advances that we find in our daily lives, such as electric motors and various electronic devices.

 

Potential Experiments

Numerous experiments can be performed with our lab setup. Users can observe how the strength of the magnetic field varies with the current that generates it. They can explore the fundamental principles of electromagnetic induction, visualizing the link between a changing magnetic field and the induced electric current. By adjusting the probe's distance from the field, they can experimentally verify the inverse square law of magnetism, delving into the intricate relationship between field strength and distance.
