Question
The magnetic lines of force around a current-carrying straight conductor are in the form of:
- Coaxial cylinders
- Concentric circles
- Parallel lines
- Concentric spheres
Hint:
Magnetic lines of force or magnetic field lines can be used to visualise the magnetic field that surrounds a current-carrying conductor.
The correct answer is: Concentric circles
The magnetic lines of force around a current-carrying straight conductor are in the form of concentric circles.
- When the current is in the straight center, the conductor holds it perpendicular.
- The center of the conductor forms the first circle of the magnetic field.
- The straight current-carrying conductor forms the magnetic fields in concentric circles.
- Magnetic lines of force or magnetic field lines can be used to visualise the magnetic field that surrounds a current-carrying conductor.
- A straight current-carrying conductor's magnetic field lines have the shape of concentric circles, with the centre located at the conductor's axis.
