Faraday's Electromagnetic Scientific Investigation
Before you begin the scientific investigation below, make sure to download the Faraday's Electromagnetic Scientific Investigation Report. As you complete this scientific investigation, fill in any needed information on the report template. If you need more information about each section of the report, please visit the Developmental Module.
This scientific investigation is available below or in a printable version.
Electromagnetic waves can have wavelengths much shorter or much longer than those that are visible to the human eye. This simulation will explore the electric and magnetic properties of electromagnetic waves and how these properties allow them to travel through space.
Objectives
In this scientific investigation, you will:
Hypothesis
Using the three Procedure and Data Collection sections below, read through the procedural information for this scientific investigation. Based on your understanding of the procedure, develop your own hypotheses which describe your expected results. What do you think is the relationship between motion of an electric charge and the direction of a magnetic field? Record these hypotheses in the Hypothesis section of your Faraday's Electromagnetic Scientific Investigation Report.

Conclusion
Using the Conclusion section of your Faraday's Electromagnetic Scientific Investigation Report, compose three to four sentences describing an overall conclusion about the relationship between the characteristics of electromagnets that are variable and the effects each variable has on the magnetic field's strength and direction. Were your hypotheses true or false, and how do you know? Use the data and notes that you collected from your simulation experience to form your conclusion. Make sure that you include information that you gained from data analysis to support your conclusion.
Experimental Sources of Error
On your Faraday's Electromagnetic Scientific Investigation Report, provide responses to the following questions: Are there any sources of error? If so, what are they and what could be done to minimize error?
