Concept explainers
To explain: The given situation.
Explanation of Solution
Introduction:
Oscillating
Consider the figure shown below.
The slots in a piece of pivoted metal bar limit induced eddy currents to several very small loops rather than very large loops. These very small current loops have low magnetic flux due to their small fields, which creates less emf and small eddy currents. The slotted bar falls more quickly through the magnetic field.
Conclusion:
Eddy currents are repulsive as well as attractive.
