CAPE Physics Unit 2 · 2008 (Rest of Region) · Paper 2 · Question 4(b)(ii)

Figure 4(a) shows a metal ring placed on top of a coil with an iron core. A current is suddenly started in the coil.

Describe and explain the motion of the ring, if any, when a slot is cut into the ring as shown in Figure 4(b).

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