PHY 102 Electromagnetic Induction 2 Objective Question
Take CBT

Question

What are 'Eddy Currents'?
Options
A Currents flowing in open circuits
B Currents flowing in a straight wire
C Circulating currents induced within metallic parts of a system (like a transformer core) due to changing magnetic flux
Correct Answer
D Static charges accumulating on a surface
Correct Answer

Option C is the correct answer.

Detailed Explanation

Page 25 defines them: 'The induced emf within this metallic part of the system causes a circulating current to flow around it and this type of core current is known as an Eddy Current.' Page 28 further elaborates.

Hint

These currents are characteristic of conductors experiencing changing magnetic fields, often in solid metallic structures.
