Segment 1 In the last lesson you learned about the math
relation of current voltage, resistance, power, current. In this lesson, you will learn about electromagnatism
and the effects of elec magnetism. As you explore magnetism, you will see how
magnetism and electricity are very closely related. First, some basic magnetic terms will be identified,
then magnetic properties of materials will be discussed, followed by a discussion of
electro magnetism. The final topic will be applications of electromagnetism.
