Worked Solution & Example Answer:Figure 11 shows the shape of the magnetic field near a bar magnet - Edexcel - GCSE Physics - Question 5 - 2022 - Paper 1
Step 1
Draw arrows on the field lines in Figure 11 to show the direction of the magnetic field.
Answer
To indicate the direction of the magnetic field, arrows should be drawn starting from the North (N) pole of the magnet and pointing towards the South (S) pole. The arrows should curve around in accordance with the field lines depicted in Figure 11.
Step 2
Place a letter X on Figure 11 at a place where the magnetic field is strongest.
Answer
The letter X should be placed in the center of the magnetic field lines, specifically in the area between the North and South poles of the magnet. This is where the magnetic field is the strongest, typically depicted as the densest concentration of field lines.
Step 3
Describe two differences between the magnetic field shown in Figure 11 and a uniform magnetic field.
Answer
-
The magnetic field shown in Figure 11 is non-uniform, meaning the strength and direction of the field vary at different locations, as indicated by the varying density of the field lines.
-
In contrast, a uniform magnetic field has parallel field lines that are equidistant from each other, indicating that the magnetic field strength is constant throughout the area.
