EMI - Current in solenoid due to magnet

Click For Summary
SUMMARY

The discussion focuses on the electromagnetic induction (EMI) in a solenoid caused by the movement of a magnet. When the north pole of the magnet approaches the solenoid, the induced current flows anticlockwise, increasing from zero to its maximum as the magnet nears the solenoid. Upon entering the solenoid, the current decreases to zero due to the opposing magnetic field. As the magnet moves away, the south pole's influence causes the current to again flow anticlockwise. The final answer to the posed question is option (c).

PREREQUISITES
  • Understanding of Faraday's Law of Electromagnetic Induction
  • Basic knowledge of solenoids and their magnetic properties
  • Familiarity with the concepts of magnetic poles (north and south)
  • Ability to analyze current direction using the right-hand rule
NEXT STEPS
  • Study Faraday's Law of Electromagnetic Induction in detail
  • Learn about Lenz's Law and its application in solenoid circuits
  • Explore the right-hand rule for determining current direction in electromagnetic systems
  • Investigate the effects of varying magnetic field strength on induced current
USEFUL FOR

Physics students, educators, and anyone interested in understanding electromagnetic induction and its applications in solenoids.

The Attempt at a Solution



Suppose that N pole of magnet is facing the solenoid
considering view from magnet
when the magnet moves close ... current is anticlockwise and increase from 0 to max till magnet reach starting of solenoid
when it enters the solenoid . some part will give opposite current and thus net current starts decreasing till 0 when magnet is in middle. now when magnet moves away ... the field due to south pole increase
so again current is anticlockwise

but answer is (c)

please someone explain me this
