why magnetic field lines of current carrying circular coil appear to be straight line at the center ?
Answers
Explanation:
At every point of current carrying circular loop the concentric circles representing the magnetic field around it becomes larger and larger as we move away from the wire. At the centre of the loop the field appears as straight line.
The magnetic field pattern due to a circular coil is shown in the given figure. At every point of current carrying circular loop the concentric circles representing the magnetic field around it becomes larger and larger as we move away from the wire. At the centre of the loop the field appears as straight line.
The magnetic field lines are concentric circles at every point of a current carrying circular loop. ... At the centre of the circular loop, The magnetic field lines are straight. Each segment of circular loop carrying current produces magnetic field lines in the same direction with in the loop.
