Answer»

The MAGNETICFIELD insidethe solenoid is the sameat each POINT .
Placing an ironobjectinside the solenoidincreases the magneticfield .
Thepattern of the magneticfieldlines of the solenoid is differentfrom that of the MAGNETIC field lines of a BAR magnet.
On reversing the directionfo the currentthe solenoid is different formthatof the magnetic fieldlines of a bar magnet.
