Question

Please simplify and write the below paragraph.
The field lines due to a current in a
circular coil become straight and
perpendicular to the plane of the coil
at the centre. This is because at every
point of circular loop the concentric
circles representing the magnetic field
become larger and larger as we move
away from the wire.

Answer 1

Field lines become straight and perpendicular because every point of circular loop the concentric circles become larger and larger as we move away from the wire.
