Plan and conduct an investigation to provide evidence that an electric current can produce a magnetic field and that a changing magnetic field can produce an electric current. HS-PS2-5
Clarification Statement: none
Assessment Boundary: Assessment is limited to designing and conducting investigations with provided materials and tools.
Planning and Carrying Out Investigations
Planning and carrying out investigations in 9-12 builds on K–8 experiences and progresses to include investigations that provide evidence for and test conceptual, mathematical, physical, and empirical models.
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. (HS-PS2-5)
Types of Interactions
Forces at a distance are explained by fields (gravitational, electric, and magnetic) permeating space that can transfer energy through space. Magnets or electric currents cause magnetic fields; electric charges or changing magnetic fields cause electric fields. (HS-PS2-5)
Definitions of Energy
“Electrical energy” may mean energy stored in a battery or energy transmitted by electric currents. (secondary to HS-PS2-5)
Cause and Effect
Empirical evidence is required to differentiate between cause and correlation and make claims about specific causes and effects. (HS-PS2-5)

A team of teacher curators is working to find, review, and vet online resources that support
the standards. Check back often, as NSTA continues to add more targeted resources.
This is a description of a student experiment that teachers can adapt to allow students to prove that electric current produces a magnetic field. The sample includes a specific example of how to do the experiment which can be adapted to an inquiry in ...
This is a lab procedure during which the student investigates the strength of a magnetic field within a coil of wire using a magnetic field probe. Students will investigate how the magnetic field strength depends on the current in the wire as well as ...
