Objectives:
TEK # and SE
Lesson # 13
P.5A Research and describe the historical development of the concepts of electromagnetic forces
P.5D Identify examples of electric and magnetic forces in everyday life.
P. 5G Investigate and describe the relationship between electric and magnetic fields in applications
such as generators, motors and transformers
See Instructional Focus Document (IFD) for TEK Specificity
Key
Understandings
A moving electric charge is surrounded by a magnetic field.
An electric current can produce magnetism, which in turn can produce an electric current.
Interactions between electric and magnetic fields can be observed in everyday objects like,
motors, generators, and transformers.
Misconceptions
Students may think that larger magnets exert larger magnetic forces.
Students may think that magnets are the only objects with magnetic fields.
Students may think hat electricity and magnetism are not related in any way.
Key Vocabulary
Magnetic field
Magnetic force
Induction

Instructional Procedures
Day 1
Engage/
Explain
Engage:
Demo electric current and its effect on a compass
for students. Ask for potential explanations based on
students’ understanding of current and electricity and
magnetism.
Provide students with lab materials for
electromagnets. Have students complete lab and
create stronger electromagnets. Reverse polarity by
switching battery and recording attractions and
repulsion of temporarily charged paperclips.
Students record observations, view electromagnet
video demonstrating current and generated electric
field and then write explanation.

Conceptual Physics textbook and
hand out of power notes
and teacher review vocabulary and key concepts of
chapter 36 in Conceptual Physics. Students complete
Power Notes for Chapter 36. Assign table groups with
specializing in sections to be presented in class
tomorrow.
Day 3 Explain
Explain:
Teacher led lecture and student explanation
covering topics from Chapter 36. Previously assigned
topics will be presented by students using teachergenerated graphics. View short clips of Hewitt Drew-its
as follow-up and support.

Day 5 Explore
Explore:
Students will apply what they have learned about
electromagnetic induction to build electric motors using
wire and batteries. Students explain motion of wire
based on electrical current in magnetic field. Can use
textbook pages to help explain operation. Use Stephen
Murray Magnetic Forces Worksheet and Magnetic
Fields worksheets

Day 6
Evaluation
Evaluation:
Students take quiz over electromagnetism and
magnetic field with motors, generators.

Day 7 Explore
Explore:
Students explore applications of Lenz’s Law and
Faraday’s Law using Generator Phet simulation. Use
Chris Bines handout created on site. Students will
differentiate generators, motors, electromagnetic
induction, pick up coil and how magnetism and electric
current are related.

Day 8 Explain
Explain:
Students use Stephen Murray worksheet packet to
review electromagnetic and magnetic concepts and
introduce mathematical equations for Faraday and
Lenz’s laws and transformers.
