Electric/magnetic fields
act on objects with a
strength following the
inverse-square law
Field lines can be
drawn to describe and
understand a field
The right and left hand
rules help predict the
effect of a magnetic
field
Electric and magnetic
fields have effects on
people, animals, and
the environment (which
is why predicting
behavior of field is
important)
Charges move in
magnetic fields in
predictable ways
Prototypes help us
conduct experiments,
observe occurrences
and demonstrate/make
conclusions

Analyze ways in which natural and technological sources of electric and
magnetic fields (e.g., motors, robotics,
speakers, generators, electrostatic precipitators, superconductors and
wireless communication) can impact society and the environmental (e.g.,
changes in animal migration, health concerns and increased
communication).
Recognize that electric fields act on point charges similar to the ways that
gravitational fields act on point masses, including action at a distance and
following the inverse-square law to determine strength of field.
Draw and describe electric field lines for like and unlike point charges and
plates separated by a distance.
Examine how the electric field strength at a point varies according to the
inverse square of the distance between two charges
Solve problems related to Coulomb’s Law
including electrostatic equilibrium in one-and two-dimensions.
Represent magnetic fields using magnetic field lines.
Represent the direction of the magnetic field around current-induced
conductors, including linear wires and wire coils, using the right hand and/or
left-hand rules.
Research the characteristics of Earth’s magnetic field, including the effects
of short-and long-term changes to the field.
Analyze the direction of positive, negative and neutral
charges moving in natural (e.g., solar flares and aurorae) and man-made
(e.g., particle accelerators and MRI’s)
magnetic fields.
Design, construct and evaluate a prototype of a technology (e.g., electric
motor, generator or electromagnet) to demonstrate principles of
electromagnetism.
