MCQ

The following statement is false for Helmholtz coils

A
in Helmholtz coils, both coils are coaxial
✓
planes of Helmholtz coils are perpendicular to each other.
C
The distance between coils is equal to the radius of either coil.
D
The magnetic field produced at the central part between the coils is uniform.

✓

Answer

Correct option: B.

planes of Helmholtz coils are perpendicular to each other.

b
The magnetic field lines can cross each other.If the magnetic field lines cross each other, it would mean that magnetic field has two directions at that point, which is not possible. Hence, magnetic field lines can cross each other.
