Concept explainers
A yoga teacher tells her students to imagine their hands are magnets pulling on each other. What are the problems with this metaphor? What is a better metaphor?
Explain the correct metaphor for the statement that hands are magnets pulling on each other.
Answer to Problem 1PQ
The correct metaphor is that two magnets are repelling each other.
Explanation of Solution
Orientation of magnetic pole depends on the pole of the magnets. Similar pole of the magnet gets repel whereas opposite pole of the magnets gets attract.
In the problem, yoga teacher says that hands are magnets pulling on each other. This means hands are pulling on each other in opposite directions.
If the magnets were actually pulling each other, they would be attracting each other. The correct metaphor is that two magnets are repelling each other.
Conclusion:
The correct metaphor is that two magnets are repelling each other.
