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.
