CBSE BoardEnglish MediumSTD 10ScienceMagnetic Effects of Electric Current1 Mark
MCQ
Identify the incorrect statement: Magnetic field lines due to a circular coil is:
  • A
    Circular near the wire.
  • B
    Straight along the axis.
  • C
    Leaving both the planes.
  • D
    Perpendicular to the plane.
✓

Answer

  1. Leaving both the planes.

Explanation:

Magnetic Field Pattern due to a Circular Loop Carrying Current. The magnetic field lines are concentric circles at every point of a current carrying circular loop. The direction of magnetic field at the centre of circular coil is perpendicular to the place of the coil. i.e. along the axis of the coil.
