Question

The diagram shows a current-carrying wire passing through the centre of a square cardboard.
How do the strengths of the magnetic field at points X, Y and Z compare?
(a) equal at X, Y and Z
(b) stronger at Y than X, equal at Y and Z
(c) weaker at Y than Z, stronger at Y than Z
(d) stronger at Y than X, weaker at Z than X

Answer 1

Answer:

I think stronger at Y than X equal at Y and Z

Answer 2

Figure shows the magnetic lines of force due to current carrying coil.

The magnitude of magnetic field at the centre of coil depend on: (i) the strength of current in the coil, and (ii) the radius of coil.

Hope it helps u mate ✌️
