Understand and explain experiments showing that a changing magnetic flux can induce an e.m.f. in a circuit, that the induced e.m.f. acts in a direction that opposes the change producing it, and which factors affect the magnitude of the induced e.m.f.
The experiments should show three things: that a changing magnetic flux can induce an e.m.f. in a circuit; that the induced e.m.f. acts in a direction that opposes the change producing it; and the factors that affect the magnitude of the induced e.m.f.
