This science project was done by Melanie, who is a student at Texas School for the Blind and Visually Impaired (TSBVI).
Question
Which material nickel, aluminum, leather, or paper will affect the magnetic field the most?
Magnetic field will be measured in milliTeslas.
Definitions
The International System unit of field intensity for magnetic fields is Tesla (T). One tesla (1 T) is defined as the field intensity generating one newton (N) of force per ampere (A) of current per meter of conductor. A magnetic field of one tesla is quite strong. That is why magnetic fields are usually expressed in microtesla (µT). Typical values of field intensity for some magnetic fields are:
The nickel will affect the magnetic field as measured with the mT (milliteslas) the most.
Four materials used in the experiment
Materials
Vernier Talking LabQuest
Vernier magnetic field sensor
magnets
aluminum foil
paper
leather
nickel
Procedure
Gather all materials need for this project.
Put the sheets of paper in between the two tables and places the magnet to the right of the paper about three in a half centimeters.
Connect the lab quest.
Using the ruler measure fifteen centimeters from the paper and use the lab quest to measure the teslas.
Record your measurement in your data table.
Move the wand from the lab quest five centimeter closer to the paper.
Record the new measurement in your data table.
Move the wand five more centimeter closer to the paper.
Record the new measurement in your data table.
Repeat this process using the nickel, aluminum sheet, and the leather instead of the paper.
Clean lab area.
Write your results and your conclusion, be sure to compare your results to your hypothesis.

Data
From 5cm
paper: .2234 milliteslas (mT)
leather: .0484 mT
aluminum: .0289 mT
nickel: .3181 mT
From 10 cm
Paper : .0803 millitesla (mT)
Leather: 0406 mT
aluminum: 0741 mT
nickel : .0700 mT
From 15 cm
paper: .0336 mT
leather: .0465 mT
aluminum: .0383 mT
nickel : .0421 mT
Conclusion
When measured from 5cm, the nickel did affect the magnetic field the most. My hypothesis was correct
Other materials could be used instead of the four chosen for this experiment.
NGSS Standards:
Plan and conduct an investigation individually and collaboratively to produce data to serve as the basis for evidence, and in the design: decide on types, how much, and accuracy of data needed to produce reliable measurements and consider limitations on the precision of the data (e.g., number of trials, cost, risk, time), and refine the design accordingly.
