Day 07 - Worksheet B

Today we're covering Worksheet B, which picks up from what you learned yesterday. There is a specific way I expect you to document your work, which I will demonstrate at the beginning of class. Be sure to follow that standard because on the test I will assign points based on the format.

coil

a layered loop of conductive material (such as copper); current through this loop will produce a magnetic field

commutator

a cylinder with a break in it such that as it spins it keeps breaking the circuit for a moment to allow a reversal of current

current

in electronics, it is the movement of electrons through a circuit; this movement can be direct (flow) or alternating (vibration)

electromagnetism

the physics invovled with the flow of electrons and their magnetic fields

magnetic field

the accumulation of force from millions of electrons aligned in the same direction, making the substance behave like an ionic element
