Eddy currents are induced in
Asingle thin wires (typical)
Ball dielectrics
Cbulk conductors in a changing magnetic field
Dsuperconductors only
Answer & Solution
Correct answer: C. bulk conductors in a changing magnetic field
1. When a solid conducting body experiences a changing magnetic flux, loops of induced current form within its bulk.
2. These circulating currents are called eddy currents.
3. They dissipate energy as heat and are used in electromagnetic braking.
