Magnetic force fields will pass through any material that is Not Magnetic itself, and does not have a magnetic field in it or surrounding it (like a wire carrying a current). When a magnetic field encounters a magnetic material the field is contained by it. This is the purpose of a "KEEPER", a metal bar that is placed across the Poles of a Horseshoe magnet. It 'Keeps' the Field in the magnet so to speak. This helps maintain the magnets strength.
A magnetic field is caused by the movement of electrons. If there are no moving electrons, there is no magnetic field. Even in a permanent magnet, the electrons are spinning. And there is an unbalance between the spin directions. We arbitrarily assign north and south to the poles of a magnet. A fundamental law of magnetism is 'Like poles repel, unlike poles attract'. Hope that is what you want.

Yes
Yes.
does magnetic forces pass through cardboard? <><><><> Very easily. Lay a paperclip on a sheet of cardboard. Place a magnet beneath the cardboard. When you move the magnet, the paperclip will also move.
yes answer 2: No, magnetism can only pass through non magnetic materials.
No, magnetic fields can only pass through non-magnetic objects (e.g cloth)
You can use a device that detects magnetism. A compass needle may suffice.
Iron has a very high permeability. So it lets maximum number of Magnetic lines of force to pass through it. The closer is the ironic conductor to the magnet, more is the number of lines of force passing through the ironic object. That is why the magnet attracts the ironic object.
yes, they pass through vacuum
No of lines of force can pass through the unit area of magnetic field
Yes!
yes
In a moving coil galvanometer, soft iron core intensifies the magnetic field through it. this causes maximum number of magnetic field lines to pass through the coil.
I need to find this answer and what we need to do this science project?
It is due the fact that iron has higher permeability than air.

A moving iron galvanometer is used to intensify the magnetic field by reducing the length of air gap across which the magnetic flux has to pass.
magnetic flux will be induced its use to rotate the shaft or given some force
