Relevant NGSS MS and HS E&M Standards

In this set of questions, we focus on ideas relevant to a beginning student: how do electricity and magnetism relate to one another? What are electric and magnetic fields, and how are those related to the sources of these fields, like charges, currents and magnets?

Concepts in E&M are complex and often involve an understanding of forces, fields, energy, atomic structure, etc. - In any one problem, then, students' ideas might touch on a number of concepts. Drafting questions that targeted ideas in high school physics was challenging. Many of the prompts here are introductory (what causes an object to have a charge/ be magnetic).

HS-PS3-5. Develop and use a model of two objects interacting through electric or magnetic fields to illustrate the forces between objects and the changes in energy of the objects due to the interaction.
