I have this little LED flashlight/ radio combo gadget that you recharge by turning a crank on it. Will I still be able to crank it up and work it after and EMP or Nuke strike?

This is something I've been pondering over for years!
Is it possible to magnetize a steel ball, say a 1/2" diameter ball-bearing, so that all the 'North' poles act outwards from the surface and all the 'South' poles act inwards towards the center ? And if it could be done, would it act like a magnetic monopole ? What would it do, how would it behave in the presence of other magnetic fields ?
