You haven't given us much to go on. Without the engineering calculations it's not possible to accurately specify the correct motor for you. If you want to guess at it, get a relatively cheap one, and if that doesn't work, get a stronger one.

so what we have, its a stick, its a magnet, it has to spin.
That is not sufficient information for anyone to help you.
How much does the magnet weigh
How fast does it have to spin
How long is the stick
How accurate does the spin rate need to be
How fast does it need to get to that spin rate
How long does it have to take to stop when you turn it off.
Just a few of the questions that have to be answered before anyone can make any suggestions.

Ok... here it is
How much does the magnet weigh... Dont know because i couldnt weight it on the scale because its magnet... its farely light
How fast does it have to spin... slow... from i would say 50-80 rpm or so
How long is the stick... about 15 cm
How accurate does the spin rate need to be... VERY!
How fast does it need to get to that spin rate... not fast... its installation so its would be on for some time
How long does it have to take to stop when you turn it off.... not important

You will have to use a geared DC (or AC) motor to get the accurate velocity that you need, a stepper will not do it.
50 to 80 rpm is very achievable with even the cheapest geared motor.
