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.

- An object is placed 24.1 cm to the left of a diverging lens (f = -6.51 cm). A concave mirror (f= 14.8 cm) is placed 30.2 cm to the right of the lens to form an image of the first image formed by the lens. Find the final image distance, measured relative to the mirror. (b) Is the final image real or virtual? (c) Is the final image upright or inverted with respect to the original object?arrow_forwardConcept Simulation 26.4 provides the option of exploring the ray diagram that applies to this problem.
