A crank with an electromagnet and an electric circuit
2
For this term’s mini- PAT, you will work on your own and as part of a group to
build a crane that can be used to pick up pieces of metal. You will work
through all the stages of the design process while you build a model of a crane
with an electromagnet. Your teacher will assess you on all the stages of the
design process.
The company wants you to design and build a model crane that:
Should be a simple frame structure,
Should be made strong, stiff, and reinforced through triangulation,
Should work with a pulley and a crank mechanism,
Should pivot, or it should raise and lower its arm,
Is made from any materials.
Some can be bought, while others can be simple materials such as
paper dowels.
The crane should have an electromagnet attached to its arm.
The electromagnet:
Should have a soft iron core made from a bundle of short lengths of iron
wire,
Must have a switch so that it can be switched on and off,
Must be strong enough to pick up several steel paper clips, nails, or
coins.
Design Brief with specifications and constraints
Ask yourself:
What is the problem?
Who is the solution for? Who will benefit from it?
What should the solution do?
Will it benefit or harm the community?
Scenario: Sorting magnetic and non-magnetic metals
3
A scrap-metal dealer sorts magnetic and non-magnetic metals into separate
piles for recycling. The simplest way to do this is to use a crane with a magnet
BUT it is difficult to remove the metals that do stick to permanent magnets.
They need a magnet that can be switched on and off.

How to make an electromagnet
Please ask an adult to assist you if you try this at home. If you want to make an
electromagnet, these are the steps you must follow:
You will need:
A large iron nail (approximately 50mm or 60mm long)
Thinly coated copper wire
A dry-cell battery, e.g. a penlight battery
Electrical tape
A pair of scissors or a wire cutter
Iron filings, paper clips and other magnetic items.
Method:
1. Wrap the thinly coated copper wire around the nail.
2. Use the scissors, or wire cutter, to cut the excess wire.
3. Leave at least 5mm of wire uncovered at both ends of the nail.
4. The wires must not overlap when you wrap them around the nail.
5. Attach the wires to the battery terminals by following these steps:
a) Peel the plastic coverings off the copper wire.
b) Attach the one end to the positive terminal of the battery.
c) Attach the other end to the negative terminal of the battery.
d) Use electric tape to stick both ends of the wire to the battery
terminals to keep them in place.
6. Use the iron filings, paper clips and other magnetic items to test the
electromagnet.

Sequence of Manufacture of an Electromagnet Crane
You are going to present the steps you will follow to build the model as a
“flowchart”.
Flowcharts are sometimes called flow diagrams.
Flow charts are designed to make information easier to understand.
They are fun to use because you can use colours and pictures instead
of just words.
You will make a process flowchart. A process flow chart shows the
method or process of making something from start to finish.
How to make a flowchart
The first shape identifies the topic or the first step of the process.
Arrows show the direction of the process from the first step to the end.
Follow the steps to read the process in the correct order. They can run
horizontally or vertically.
The last shape is used for the last step in the process.

Make an Oblique Drawing
13
1. Choose one part of your model to draw in oblique view.
2. You should draw the part to scale. You can draw it to larger than it is on
the model. If you draw it twice the real size, show the scale as 2:1.
3. Draw the part on the grid paper on the opposite page.
Oblique drawing
Draw the lines for length and height straight up and straight across,
exactly like the front view of a box in a 2D.
Oblique drawings should be scale drawings. For the front view of an
oblique drawing, use true scale measurements. So, if the length of the
object is 600 mm and the scale is 1:10, you draw the length as 60 mm.
indicate the scale below your drawing.
Corners are projected at a 45° angle and the depth measurement must
be half the true scale measurement. So, if the depth is 300mm and the
scale is 1:10, you must draw the breadth line to 15 mm.
Make sure that you have given your drawing a heading.
Scale
We often draw objects smaller than they really are so that the drawing
can fit on a page.
A scale drawing of 1:4 is four times smaller than the real object. If the
object is 400 mm wide, we draw its width as 40 mm.
