Building a Magnetic Damper with Nano Tech

Click For Summary
SUMMARY

The discussion centers on the feasibility of constructing a magnetic damper using nanotechnology and composite materials. Specifically, the use of mu-metal and silicon-steel layers is proposed as a method to shield against magnetic fields. Participants clarify that mu-metal is indeed a type of silicon steel, and the term "magnetic damper" can refer to magnetic shock absorbers. The conversation emphasizes the importance of understanding material properties in the design of effective magnetic dampers.

PREREQUISITES
  • Understanding of mu-metal properties and applications
  • Familiarity with silicon-steel composites
  • Knowledge of magnetic damping principles
  • Basic concepts of nanotechnology in material science
NEXT STEPS
  • Research the properties and applications of mu-metal in electromagnetic shielding
  • Explore the design and functionality of magnetic shock absorbers
  • Investigate advancements in nanotechnology for composite materials
  • Study the principles of magnetic damping and its engineering applications
USEFUL FOR

Engineers, material scientists, and researchers interested in magnetic damping technologies and the application of nanotechnology in composite materials.

Can we build a Magnetic damper ( for magnets ) with nano thec or any tech ?
 
Engineering news on Phys.org
So there are not any magnetic insulator ? !
 
A composite of mu-metal and silicon-steel layers can be provides a shield against all magnetic fields ?

Sorry, but it's not at all clear what you're asking. Mu-metal, for one, is a silicon steel. Also, "magnetic damper" can be used to refer to a magnetic shock absorber.
 

Thread 'uA709 op amp compensation'

Most likely this can only be answered by an "old timer". I am making measurements on an uA709 op amp (metal can). I would like to calculate the frequency rolloff curves (I can measure them). I assume the compensation is via the miller effect. To do the calculations I would need to know the gain of the transistors and the effective resistance seen at the compensation terminals, not including the values I put there. Anyone know those values?
