GCSE Edexcel Physics Combined Science Permanent & induced magnets: 2 (a) Figure 3 shows some object

Question

2 (a) Figure 3 shows some objects and words describing these objects.
Draw one line from each object to its description.

2 (b) Figure 4 shows a wire passing through a piece of card.
The wire carries an electric current.

(i) Draw one magnetic field line on Figure 4, to show the shape of the magnetic field produced by the current.

(ii) Draw one arrow on the field line you have drawn to show the direction of the magnetic field.

2 (c) A student measures the strength of the magnetic field at several distances from the wire in Figure 4.
Figure 5 shows most of the student’s results.

(iii) Use the graph in Figure 5 to calculate the change in strength of magnetic field when the distance from the wire changes from 4 cm to 8 cm.

(iv) State one other factor that affects the strength of the magnetic field.
