Maxwell's Cork Screw Rule 3d Animation

Main ideas / concepts

• The video explains how to determine the direction of the magnetic field produced by a current-carrying conductor.
• It compares two equivalent methods:
  • Right-hand grip rule
  • Maxwell’s corkscrew rule (a 3D/corkscrew visualization approach)

Methodologies / instructions (step-by-step)

1) Right-hand grip rule

• Hold the conductor in your right hand.
• Ensure your fingers wrap around the conductor.
• Set your thumb to point in the direction of the current.
• Then interpret the result:
  • The direction of the wrapped fingers gives the direction of the circular magnetic field around the conductor.

2) Maxwell’s corkscrew rule

• Visualize a right-handed corkscrew rotated in space.
• Rotate the corkscrew so that:
  • The point of the corkscrew moves in the direction of the current.
• Conclusion:
  • The direction the corkscrew rotates is the direction of the magnetic field around the conductor.

Key takeaway / lesson

• Both rules determine the circular magnetic field direction around a current-carrying wire, and their outcomes are consistent:
  • Thumb/current → fingers (right-hand rule)
  • Corkscrew point/current direction → corkscrew rotation (Maxwell’s rule)
