The magnetic moment is defined as the property of the material which interacts with the applied field.

It is generally given as M=2ml

Where l= length of the material

m= magnetisation of the material.

Here the incorrect answer is Magnetic moment of solenoid does not change when iron rod is inserted in it.

When an iron core is put inside a solenoid,

It's dipole aligns with the dipole of the solenoid.

Hence, the total magnetic moment of the solenoid increases.
