The diagram shows the result when a student placed a magnet under a piece of paper, then sprinkled iron shavings on the paper.
The magnetic material is distributed this way because magnets
a
have magnetic fields that repel magnetic materials and push the shavings away.
b
have multiple magnetic fields that attract the shavings with different strengths.
c
have uneven magnetic fields that attract the shavings in random patterns.
d
have magnetic fields that flow from one pole of the magnet to the other.
d. have magnetic fields that flow from one pole of the magnet to the other.
d. have magnetic fields that flow from one pole of the magnet to the other.
The correct answer is:
d. have magnetic fields that flow from one pole of the magnet to the other.
The reason the magnetic material, such as iron shavings, is distributed in a specific pattern when a magnet is placed under a piece of paper is because magnets have magnetic fields that flow from one pole of the magnet to the other.
To understand this, we can explain the process step by step:
1. When a magnet is placed under a piece of paper, it creates a magnetic field around it. The magnetic field is produced by the alignment of the magnet's atomic Ions.
2. Iron shavings are attracted to magnets because they are ferromagnetic materials. This means that their atoms have unpaired electrons, which can align with an external magnetic field.
3. The magnetic field of the magnet attracts the iron shavings and causes them to align along the lines of the magnetic field. This alignment creates the pattern seen in the diagram.
So, the distribution of the iron shavings in the diagram is a result of the magnet's magnetic field flowing from one pole (usually the north pole) to the other (usually the south pole), causing the shavings to align along these magnetic field lines.
