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?

equal at X, Y and Z

stronger at Y than X, equal at Y and Z

weaker at Y than Z, stronger at Y than Z

stronger at Y than X, weaker at Z than X

The closer to the wire, the stronger is the magnetic field strength. Since, the magnetic field is circular. Y is the closest followed by X than Z.
