Question:
Can magnetic fields created by magnets of any
sort, affect non-magnetic material?
Replies:
Yes, magnetic fields affect non-magnetic things, but you might
not notice the effects they produce. The Hall effect, for example,
produces a voltage proportional to the magnetic field across a
non-magnetic semiconductor.

John H.,
A magnetic field can affect any material with an electric charge, so long as
the charged object is moving across the magnetic field. The faster the
electric charge crosses the magnetic field, the harder the stronger the
force felt.
A good example is an electric motor. Electric current flows through coils,
passing through a magnetic field. The magnetic field pushes the electric
current, and the coils that contain the current, sideways. This causes the
motor's shaft to turn. Now you have an electric motor.

Yes. A moving magnetic field will induce a counter magnetic field in any
conductor.
This is used in laboratory balances to damp the oscillations when weighing
objects.
