Yes it is
No.
No, the magnetic field is not made of matter. It is a force that is produced by the movement of electric charges.
Magnetic photons interact with matter in the presence of a magnetic field by causing the alignment of electron spins within the material. This alignment can lead to changes in the material's properties, such as its conductivity or magnetic behavior.
Yes it is
Electron Magnetic Waves will propagate in the absence of matter
A British 10p coin, and all British coins for that matter, are not magnetic.
Larger magnetic fields.
Yes, plasma is a state of matter. It is an excited gas susceptible to magnetic and electric fields.

The CD is matter, the information is carried as deformations in/of the matter. In that way it is no different to magnetic tapes and vinyl records.
A magnet can be used to separate magnetic materials from other substances by attracting the magnetic material while leaving non-magnetic materials behind. This process is known as magnetic separation and is commonly used in recycling and mining industries.
Yes, amps matter in an electromagnet because they determine the strength of the magnetic field generated. Increasing the electric current flowing through the coil increases the magnetic field strength, while decreasing the current weakens the magnetic field. It is one of the key factors that affect the performance of an electromagnet.
