Question

A teacher sprinkles some iron shavings on a clear tray . She places two magnets in the shavings with the north ends facing each other . Based on the cause-and-effect relationship between the magnets, which phenomenon is the teacher modeling for her students ?

Answer 1

The teacher is demonstrating the concept of magnetic repulsion by placing iron shavings around two magnets with like poles facing each other.

Step-by-step explanation:

The teacher is modeling the phenomenon of magnetic repulsion for her students. When the two magnets are placed with their north ends facing each other, the iron shavings align to illustrate the invisible magnetic field lines. These lines show that the magnets are repelling each other because like poles (north to north or south to south) repel. If the magnets were instead placed with one north end facing the south end of the other magnet, the iron shavings would form a different pattern, showing the magnetic field lines curving from one pole to another, indicating magnetic attraction.

The patterns formed by the iron shavings are used to visually represent the direction and strength of the magnetic field around the magnets. When the two bar magnets are placed side by side with opposite poles facing each other, the iron filings would show a pattern where the lines emerge from the north pole of one magnet and curve to enter the south pole of the other, demonstrating attraction. This hands-on experiment is a classic way to explore and understand magnetic fields and the interactions between magnetic poles.

Answer 2

Field of repulsion.

Step-by-step explanation:

An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).

This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.

Cause and effect can be defined as the relationship between two things or events in which an occurrence one (cause) leads to the occurrence of another (effect).

In this scenario, a teacher sprinkles some iron shavings on a clear tray. She places two magnets in the shavings with the north ends facing each other. Based on the cause-and-effect relationship between the magnets, the phenomenon the teacher is modeling for her students is field of repulsion.

Generally, the two north ends of a magnet have the same polarities and as such are considered to be like charges.

Hence, the field of repulsion is a phenomenon that is based on the fact that like charges repel while unlike charges attract. Thus, the north end of a magnet would repel the north end of another magnet placed beside it.
