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 illustrate the direction of the magnetic field lines, draw arrows starting from the north (N) pole of the magnet and pointing toward the south (S) pole. The arrows should curve outward before returning to the magnet, showing the shape of the field around the bar magnet.
Step 2
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; it varies in strength and direction around the magnet, with more concentrated lines of force near the poles and more spread out lines elsewhere. In contrast, a uniform magnetic field has equal strength and direction throughout the space.
-
The shape of the magnetic field around the bar magnet is curved, indicating a dipole pattern, while a uniform magnetic field usually appears as parallel lines, indicating a consistent field without variations.
