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
Draw the shape and direction of the magnetic field between the two magnets.
Answer
To correctly illustrate the magnetic field between the two magnets, draw at least four lines emanating from the N poles. These lines should not intersect, and they should be directed away from the N poles towards the S poles of the respective magnets, resulting in a clear representation of the magnetic field lines.
Step 2
Describe the forces acting on the upper magnet.
Answer
The forces acting on the upper magnet can be described as follows:
-
Magnetic fields interact: The upper and lower magnets are within each other's magnetic field, leading to interactions between them.
-
Repulsion Forces: There is a repulsive force acting between the two magnets since both have their north poles facing each other. This force pushes the upper magnet away from the lower magnet.
-
Gravitational Force: The weight of the upper magnet also acts downwards due to gravity, creating an opposing force against the magnetic repulsion.
Since the upper magnet floats, we can conclude that these forces are balanced, indicating equilibrium.
