Question
Which type of magnetic field lines are formed near the current-carrying circular coil?
- Circular
- Straight line
- Ellipse
- Magnetic field is zero at the center.
Hint:
Circular
The correct answer is: Circular
The magnetic field lines are concentric circles at every point of current carrying circular loop.
The magnetic field lines are straight at the center of the loop and the lines of force are in same direction
The magnetic field lines at the center of the loop are perpendicular to the plane of the loop carrying current.
