Electromagnet
Writing a hypothesis
To get level 6
Abstract ideas. You need to give a good explanation based on the
domain theory of magnetism about why the magnet gets stronger
as you increase the current or power pack voltage or the number
of turns. Diagrams are essential.
To get level 7
Linked ideas from a variety of sources. You need to also explain
what is happening inside the wires where the current is flowing
and why this produces a magnetic field. You also need to say
where your ideas/ information came from (linked to your research)
To get level 8
Quantitative prediction. This means a number pattern or predicting
the shape of a graph. Do not start to think about this until I have
read your hypothesis and agreed that it meets level 7.
