Question

In a uniform magnetic field, the field lines are:

  1. Curved
  2. Parallel and equidistant
  3. Parallel but not equidistant
  4. Nothing can be said

hintHint:

A magnetic field is a visual representation of how magnetic force is distributed in the space around and inside a magnetic object

The correct answer is: Parallel and equidistant


    • A magnetic field is a visual representation of how magnetic force is distributed in the space around and inside a magnetic object
    • The magnetic field is mathematically defined as a vector field.
    • If the magnetic induction has the same magnitude and direction at all points in the vicinity, the magnetic field is said to be uniform. A uniform magnetic field is one in which the magnetic field lines move in a straight line from the North to the South Pole of a magnet
    • The magnetic field is said to be non-uniform if the magnetic induction varies in magnitude and direction across an area
    • We can conclude that the magnetic field lines of a uniform magnetic field move in a straight line with equal magnitude and are parallel to each other.
