Calculating Peak Velocity of a Magnet Under Continuous Magnetic Force

Click For Summary
SUMMARY

The discussion focuses on calculating the peak velocity of a magnet (MagX) weighing 0.03 lbs, subjected to a continuous force of 3 PSI from another magnet (MagY) positioned 0.5 inches away. The key formula used is derived from the conservation of energy principle, specifically Fd = ½mv², where F is the force converted from PSI to pounds, d is the distance, and m is the mass of MagX. The absence of friction simplifies the calculation, allowing for a straightforward application of the kinetic energy equation to determine the peak velocity.

PREREQUISITES
  • Understanding of basic physics concepts, particularly force and energy.
  • Familiarity with unit conversions, specifically PSI to pounds.
  • Knowledge of the kinetic energy formula and its application.
  • Basic understanding of magnetism and magnetic forces.
NEXT STEPS
  • Learn about unit conversion techniques, especially converting PSI to pounds.
  • Study the principles of kinetic energy and its relation to motion.
  • Explore the effects of friction on moving objects and how to factor it into calculations.
  • Investigate the behavior of magnets in motion and the forces acting on them.
USEFUL FOR

Students in physics, engineers working on magnet-based projects, and anyone interested in the dynamics of magnetic forces and motion calculations.

Homework Statement


Imagine you have a magnet (Henceforth named MagX) which weighs .03lbs, and it is being continuously pushed by another magnet's polar likes (Henceforth named MagY) with a force of 3 PSI. Is it possible to find the peak velocity of MagX, assuming that MagY stays at a constant distance of 0.5" away from MagX?

Friction is not factored in.
The dimensions of MagX are 2.0" x 0.5" x .125"

This isn't for "Homework", but it's relevant to a project which I cannot elaborate on.
I apologize if the question doesn't make sense or is too vague. I admit that I am no physics major and I honestly have no idea where to go from here.

Thank you for your time.

Since you know the force in psi, you can convert that into a force (in lbs) by multiplying by the area and then apply conservation of energy.

force*distance = change in kinetic energy of magX (assuming 0 initial KE)

Fd = ½mv2

v would give the velocity in some units which I am not sure of since I never really used those units.
 
That's exactly what I needed to know. Thank you so much for the help rock.freak!
