Induction current- velocity dependence

Click For Summary
SUMMARY

The discussion centers on the relationship between induction current and the velocity of a linear movement in a shock absorber system utilizing a cylindrical permanent magnet. The user references Faraday's Law, specifically the equation E = vxB(Rext-Rint), to express the electromotive force (E) in relation to velocity (v) and magnetic field induction (B). However, there is uncertainty regarding the directionality of the vectors involved. For accurate calculations of forces on permanent magnets, the user is advised to utilize ANSYS Maxwell software.

PREREQUISITES
  • Understanding of Faraday's Law of Electromagnetic Induction
  • Familiarity with the principles of electromotive force (EMF)
  • Basic knowledge of magnetic field induction and its components
  • Proficiency in using simulation software, specifically ANSYS Maxwell
NEXT STEPS
  • Research the application of Faraday's Law in electromagnetic systems
  • Explore the functionality and features of ANSYS Maxwell for magnetic field simulations
  • Study the dynamics of shock absorber systems and their damping coefficients
  • Investigate the vector relationships in electromagnetic fields and their implications on force calculations
USEFUL FOR

Engineers and researchers in the fields of mechanical engineering, electromagnetism, and automotive design, particularly those involved in the development and optimization of shock absorber systems.

Hello,

I have to put the cylindrical permanent magnet into shaft of the shock absorber with coil around it. I need such a system which let's me to control the damping coefficient of the shock absorber so that's why a have to know the current. I can't find anywhere the relation between induction current and for example velocity of linear movement of the shaft, by the use of Faraday's Law I found that it should be that
E = vxB(Rext-Rint)
where E - electromotive force, v - velocity, B - magnetic field induction, Rext - external radius, Rint - internal radius of the magnet
But I don't think that its true because B and v vectors have the same direction.
Please help
