Re: Newton's Cradle

They will become magnetized from the earth's weak field. Each impact
jostles the domains enough for them to settle back a bit more aligned.

Try reversing it's 'usual' orientation and slam it for a while.

An AC solenoid or a tv screen degaussing coil would help.

non magnetic spheres.

Is there a convenient way to demagnetize a sphere?

Thanks, David Abineri
