Question

(i)How are eddy currents reduced in a metallic core ? (ii) give two uses of eddy current

Answer 1

Answer- thinner core will ensure there are lower Eddy currents.

Step-by-step explanation:

(i) eddy currents are the backward currents that are responsible to resist the flow of forward current. their characteristics are production of heat. they are used in mettalic core to generate heat.

(ii) two uses of eddy currents are: (a) heat generation (b) used in house hold current meters to measure power consumption.

Answer 2

Answer:

The eddy's current are a cause of energy loss in alternating current (AC) inductors, transformers, electric motors and generators and other AC appliances or machinery they are reduced by laminating the magnetic cores. Eddy currents are reduced by using multiple plates instead of using a large plate.
