Worked Solution & Example Answer:Figure 3 shows two magnets with their N poles facing each other - Edexcel - GCSE Physics Combined Science - Question 3 - 2023 - Paper 2
Step 1
On Figure 3, draw the shape and direction of the magnetic field between the two magnets.
Answer
To illustrate the magnetic field between the two magnets, draw at least four lines starting from the north pole of one magnet and curve them toward the north pole of the other magnet. Ensure that the lines are evenly spaced and do not intersect or cross over each other. At the ends of these lines, indicate the direction with arrows pointing away from the north poles.
Step 2
Describe the forces acting on the upper magnet.
Answer
The upper magnet experiences several forces:
-
Repulsion due to the lower magnet: The two north poles repel each other, which means the upper magnet experiences a force pushing it upwards due to the repulsive magnetic field.
-
Weight (gravitational force): The upper magnet is also pulled downwards by its weight, which depends on its mass and is acting toward the Earth's center.
-
Equilibrium of forces: The forces acting on the upper magnet are balanced. The upward force of repulsion from the lower magnet is equal to the downward force of gravity, allowing it to float stably in the air.
