Question
In a uniform magnetic field, the field lines are:
- Curved
- Parallel and equidistant
- Parallel but not equidistant
- Nothing can be said
Hint:
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.
