Electromagnetism (wires/batteries/magnets)

Board Preview Video
Here we focus on learning the common circuit components and this leads into understanding the amazing relationship between electricity and magnetism.

We work through a number of boards, building knowledge as we go, ending with you will have a good idea how so many electrical gadgets work! It is suggested that you work through this section before the ones on Electronic Components and Green Energy.

Maths expectations:


WE01

Board WE01 Circuit Basics
This board contains a very simple circuit, but it's important we understand what makes up a circuit before be move on to more complex ones.

Explained: circuit, conductor, load, supply, switch.

Cur. Ref: SCN 1-09a


WE02

Board WE02 Switches
On this board we can see working examples of different types of switches used on the other boards and commonly used in electrical applications.

Explained: rotary switch, toggle switch, button switch, serial connections, parrallel connections, 2-way switches, crossover switches.

Cur. Ref: SCN 2-09a


WE03

Board WE02 Switch Practical
Here we can use the board with banana leads to try out different switch types, combinations and wiring options.

Explained: banana leads, banana sockets, rocker switch, single pole, double pole, single throw, double throw.

Cur. Ref: SCN 2-09a


WE04

Board WE04 Measuring Electricity
Here we introduce voltage and current and the units of volts and amps.

Explained: current, amps, electrical pressure, volts, voltage, watts, power.

Cur. Ref: SCN 3-09a


WE05

Board WE05 Parallel & Serial Connections
This board expands our understanding of voltage and current by see how they are affected by multiple devices connected in parallel and in series.

Explained: serial connections, parallel connections.

Cur. Ref: SCN 3-09a


WE06

Board WE06 Conductors
This board contains 9 different types of material, each of which can be included in a circuit to see how well electricity can flow through them.

Explained: good/poor conductors, insulators, resistance.

Cur. Ref: SCN 4-09a


WE07

Board WE07Board WE07 Magnetism
Two board here, both starting to look at the very strange world of magnets and their forces of attraction and repulsion.

Explained: magnetic field, magnetic poles, attraction force.

Cur. Ref: SCN 1-08a


WE08

Board WE08Board WE08 Electromagnetism
Now we introduce electromagnetism - the main subject of this whole section and we see how electricity and magnetism are linked.

Explained: coil, iron filings, electromagnetism, repulsive force.

Cur. Ref: SCN 4-08a


WE09

Board WE09 Trembler Bells & Relays
There are two practical uses of electromagnetism on this board, one is fun (the trembler bell) and the other rather boring (the relay).

Explained: relay switch, trembler bell.

Cur. Ref: SCN 4-08a


WE10

Board WE10 Electromagentic Forces
Now we look at the forces we get in a coil of wire when it's in a magnetic field.

Explained: electromagentic force, magnetic force, magnetic fields.

Cur. Ref: SCN 4-08a


WE11

Board WE11 Electric Motors
Here we talk about how electric motors use electromagnetism.

Explained: electric motor, brushes, 2 pole, 3 pole.


WE12

Board WE12 Creating Electricity
Now we turn everything around and see what happens when we move a coil in a magnetic field.

Explained: electromagnetic induction, microamp.
