Question

What is a primary consequence of eddy currents in electrical systems, as described in the document?
Options
A They increase the efficiency of energy transfer.
B They cause a loss of energy, transforming useful forms into heat.
Correct Answer
C They lead to a stronger magnetic field, which is always beneficial.
D They act to enhance the primary magnetic flux.
Correct Answer

Option B is the correct answer.

Detailed Explanation

Page 28 states: 'Because of the tendency of eddy currents to oppose, eddy currents cause a loss of energy. Eddy currents transform more useful forms of energy, such as kinetic energy, into heat, which isn't generally useful.'

Hint

Lenz's law principle of opposition means there's an energy cost.
