6.2 Electric Force and Field

6.2.1

State that there are two types of electric charge

hint: you should also explain what those two charge types ARE

6.2.2

State and Apply the law of conservation of charge

6.2.3

Describe and Explain the difference in the electrical properties of conductors and insulators

6.2.4

State Coulomb's Law

6.2.5

Define Electric Field Strength

6.2.6

Determine the Electric Field Strength due to one or more point charges

6.2.7

Draw the electric field patterns for different configurations

6.2.8

Solve problems involving electric

6.3 Magnetic Force and Field

6.3.1

State that moving charges give rise to magnetic fields

Hint: Also explain HOW this happens, and how we know the direction of the field

6.3.2

Draw magnetic field patterns due to currents

Expected: currents INTO the page, OUT of the page, 2 Parallel wires with currents in SAME direction, and 2 parallel wires with currents in OPPOSITE directions

6.3.3

Determine the direction of the force on a current-carrying conductor in a magnetic field

Expected: show 2-3 examples, and explain HOW the direction was determined

6.3.4

Determine the direction of the force on a charge moving through a magnetic field

same as above: show some examples, and explain HOW the direction is determined

6.3.5

Define the magnitude and the direction of a magnetic field

hint: explain how we illustrate the magnitude, and in what direction does a magnetic field ALWAYS point?

6.3.6

Solve problems involving magnetic forces, fields and currents
