A moving electric charge (moving relative to another object) will create a magnetic field around it. So if this charge moves passed a permanent magnet, their fields will interact and cause a force (basic principle of the motor effect).
However, if the electric charge is standing still in relation to the magnet, there won't be any force because the charge isn't emitting a magnetic field.
But if a 2nd magnet moves passed the still magnet and charge, neglecting the fact that the 2 magnets will affect each other, the charge and 2nd magnet now are moving relative to each other so the charge emits a magnetic field, causing a force between them. This means the magnetic field must have been there the whole time. How is it possible that the magnetic field can always be there, but not interact with the 1st magnet?
