electromag vs rare earth mag
(OP)
I tried the old make an electro mag with a nail and wire and battery with success but could not repell a rare earth magnet.
Is this possible?

1 - Attractive force between cube of Neo magnet and cube of steel
2 - Attractive force between cube of Neo magnet and cube of ferrite magnet.
(With all cubes roughly the same size)
The initially surprising thing is that 1 is stronger than 2. The reason is that the Neo is much stronger than the ferrite, so the attraction in 2 is limited by the ferrite magnet. In your case, the repulsion is limited by the dc current... and I suspect this is small compared to the attraction associated with the Neo to the iron.
