SUMMARY

The magnetic field inside a cylindrical conductor with inner radius 'a' and outer radius 'b' carrying a uniform current 'I' is zero. This conclusion is derived using Ampere's Law, which states that the magnetic field is generated by currents enclosed by a loop. Since there is no current in the hollow part of the conductor, the magnetic field remains null within that region.

PREREQUISITES
  • Ampere's Law
  • Understanding of magnetic fields
  • Concept of current distribution
  • Basic electromagnetism principles
NEXT STEPS
  • Study the application of Ampere's Law in different geometries
  • Explore the concept of magnetic field lines and their behavior around conductors
  • Investigate current distribution in various conductor shapes
  • Learn about the magnetic field outside cylindrical conductors
USEFUL FOR

Physics students, electrical engineers, and anyone interested in the principles of electromagnetism and magnetic field analysis.

why is the magnetic field just inside a cylindrical conductor with inner radii a, and outer radii b carrying a uniform current I distributed through it's croos section just 0 inside the conductor.
I used ampere's law and that surely doesn't give 0

a current produces a magnetic field whose lines of force form circles around the wire carring the current. every loop (of field lines) must inclose a current and there is no current in the hollow part of the wire.
