yes give it more space between magnet and core
ive notice that with core you dont need magnets so close as in air core!!!
second thing is the core itself maybe we sould use soft iron instead , because this ferrite core has very high reluctance maybe it dont need so much !!
u see i had the same problem my magnets were sticking co core too much ...have to read more about this reluctance...
but as i said try bigger gap
