Gambeir,

It's the material magnets are made off that is more susceptible to the induced field but really it is the induced electric field which makes a magnet.

And of proof of this is the following:
---------------------------------------------------------------
Making an steel bar a magnet by magnetic induction (double touch method)

Place a steel bar on top of two strong bar magnets facing with opposite poles each other and an air cap in between less than lenght of the steel bar so that stee bar can sit on the two magnets.

Aproach two strong bar magnets from above with inclined angles and the same polarity as the bottom magnets.

On the steel bar slide several times on its one surface the two top magnets with opposite poles in this fashion of movement

<--N|S-->

starting from the middle (|) of the iron bar.


-----------------------------------------------------------------

That proves that magnetism originates from the Bloch domain region of a magnet, its middle (|).

Try to make the steel bar a magnet with the opposite movement as described above:

N-->|<--S

good luck!...
