CAPE Physics Unit 2 · 2009 · Paper 2 · Question 4(c)

Describe how the apparatus in Figure 5 could verify Faraday's law: sketch the expected graph of e.m.f. versus motor speed, explain how the conclusion is drawn from the graph, and state which factors must be held constant.

This question uses a figure or table from the paper — you'll see it when you practise.
