Not really. Plastics are almost all hydrocarbons, and the magnetic field lines go right through plastics like the plastics were invisible. That's the short answer, but it contains the essentials.
No, look up magnetic permeability. This is a material constant describing an objects capacity to be magnetized or to allow a magnetic field to form within it. Plastics, aluminum, air, organic compounds, etc all have a permeability of around 1 which means their molecule do not magnetize. Since their molecules do not magnetize they do not affect a magnetic field which will pass through them unchanged.
because it is plastic
Yes. if it is statically charged.
Because the entire concept of magnetic field is based on the element IRON (and to a much lesser degree, Nickel). Iron content? (most metals): Magnetic. Plastic based? (no iron): Not magnetic. Simple as that.
Simple: chalk dust has no magnetic properties whatsoever, and is an insulator. As such, the magnetic field will flow right past it as if it weren't there, so it cannot position itself accordingly.
The magnetic field. If it's an electromagnet, the electromagnetic field.
No, Ceres does not have a magnetic field around it.
A black hole has no magnetic field.

A credit card is a piece of plastic with a strip of magnetic information on it. When this strip is exposed to a strong magnetic field, like in an MRI, PET scan, or CAT scan it can get erased because the magnetic field removes the magnetic information.
A non-magnetic matieral is one where there are no (or very few) free electrons to conduct the electro-magnetic field. One basic example is plastic.

no. Eris does not have a magnetic field
The magnetic field. If it's an electromagnet, the electromagnetic field.
In a combined magnetic field, a neutral point is a place where the magnetic field is zero
Things that are affected by a magnetic field, such as iron and steel can hover in a magnetic field.
Non-magnetic
Magnetic field is made up of magnetic lines.
