Which of the following will not increase the size and effect of eddy c...
Explanation:
Eddy currents are circulating currents induced in a conductor when it is exposed to a changing magnetic field. These currents flow in closed loops and can cause heating and energy losses in the conductor.
The size and effect of eddy currents can be influenced by several factors. Let's analyze each option and its effect on the size and effect of eddy currents:
a) Low resistivity materials:
- Eddy currents are directly proportional to the conductivity of the material.
- Low resistivity materials have higher conductivity, which means they allow more current to flow.
- Therefore, using low resistivity materials will increase the size and effect of eddy currents.
b) Strong magnetic field:
- Eddy currents are directly proportional to the strength of the magnetic field.
- A stronger magnetic field will induce larger eddy currents in the conductor.
- Therefore, using a strong magnetic field will increase the size and effect of eddy currents.
c) Thicker material:
- Eddy currents are inversely proportional to the thickness of the material.
- Thicker materials offer more resistance to the flow of eddy currents.
- Therefore, using a thicker material will reduce the size and effect of eddy currents.
d) Thinner material:
- Eddy currents are inversely proportional to the thickness of the material.
- Thinner materials offer less resistance to the flow of eddy currents.
- Therefore, using a thinner material will increase the size and effect of eddy currents.
Conclusion:
Based on the analysis above, the correct answer is option 'd' - Thinner material. Using a thinner material will not increase the size and effect of eddy currents.
