SUMMARY

The discussion focuses on calculating the induced current 'I' in a solenoid encircled by two semicircle magnets with strength 'B', moving at a constant velocity 'V'. The induced current can be determined using Faraday's Law of Electromagnetic Induction, which states that the induced electromotive force (EMF) is proportional to the rate of change of magnetic flux. Additionally, the force experienced by the magnets due to the induced current can be analyzed using Lenz's Law, which indicates that the direction of induced current opposes the change in magnetic flux. The orientation of the magnets is crucial; if the poles are positioned to attract each other, the magnetic lines may remain contained, potentially resulting in zero induction and force.

PREREQUISITES
  • Understanding of Faraday's Law of Electromagnetic Induction
  • Knowledge of Lenz's Law and its implications
  • Familiarity with magnetic field concepts and solenoid behavior
  • Basic principles of electromotive force (EMF)
NEXT STEPS
  • Research the application of Faraday's Law in dynamic systems
  • Explore Lenz's Law in detail and its effects on induced currents
  • Study the behavior of solenoids in varying magnetic fields
  • Investigate the relationship between magnetic field strength and induced EMF
USEFUL FOR

Physicists, electrical engineers, and students studying electromagnetism or related fields will benefit from this discussion, particularly those interested in the dynamics of induced currents and magnetic interactions.

can someone help with this calculation

two semicircle magnets N-S of strength 'B' encircle a solenoid of length 'L' and move with a constant velocity 'V'. what will be the current 'I' that is induced in solenoid. also, what force will the magnet experience because of this current (Lenz's law)
 
Physics news on Phys.org
what is the orientation of these semicircle magnets? are the poles at the end so that they attract each other and make a circle? if so, if could very well be that the induction is zero...the magnetic lines of the magnets simply stay inside the body of the magnets and have no need to go out and turn around to go from north to south. Force=0, too.
