1

Solenoid

is a coil of wire carrying an electrical current.

2

Hysteresis Loop

A curve formed by materials showing flux density as a magnetizing force is increased, decreased, increased in opposite direction, then returned to zero

3

Flux

Lines of force of a magnetic or electrostatic field

4

Coercive force

the amount of magnetizing force needed to remove residual magnetism

5

Permeability

A unit noting the ability of a material to establish lines of magnetic flux

6

Reluctance

the opposition of a material to establish magnetic lines of flux

7

How would one increase the amperage as the be readable by a clamp-on ammeter

By forming loops around one arm of the clamp and dividing the readout by the number of turns/loops

8

If you see a dot current is ___ and an X means current is flowing ____

Towards, Away ***Remember the arrow analogy, Feathers (x) shooting away
Tip (.) shooting towards***

9

Explain the right hand rule

thumb points in the direction of the force
middle points in direction of current (. or X)
index points in the direction of the magnetic field
