Because of a property called spin, electrons act like tiny magnets. Most of the time paired electrons contain opposite spins, meaning the material has a weak magnetic field. The more paired electrons a material has, the weaker the magnetic field in the material. Unpaired electrons attract and repel other material. This determines which materials unpaired electrons match up with and attract to form a magnetic domain.
Magnetic fields are cause by the movement of charge , normally electrons each atoms has a magnetic moment

One of them is how many coils go around the electromagnet. also the amout of current flow< and the type of core material.
Electricity is conducted well in substances that have lots of free electrons, or other free charge carriers. That is, charge carriers that are free to move around.
Mass affects the properties of inertia

No. Orange juice contains no magnetic material; it would perhaps lower the strength of a field, being a medium with lower permittivity, but not by any significant amount.
Thrse electrons are involved in chemical reactions.
Electricity is created by a rotating magnetic field captured by a coil. The flow of electrons creates a magnetic field.

Magnetization does not affect the mass of the material being magnetized. All the magnetizing field does is align the magnetic domains of the material being magnetized. No matter or mass is added, or "created out of energy" or the like. Nothing changes except the orientation of magnetic domains within the material being magnetized.
No, absolutely not. There are much smaller particles, first Electrons (which are part of reactions), Then Quarks that neutrons and protons are made of (and are part of reactions), and much, much smaller particles after that also are involved in chemical reactions.
The earth's magnetic field acts upon the magnetic material of the compass needle, causing it to align to the field. Thus, the compass appears to point North, which is "magnetic north". Magnetic north and "true north" are about 300 miles apart.
because chemical properties are determined by the nomber of electrons and protons and all isotops have the same number electrons and protons. they differ in the number of neutrons alone which doesnt affect chemical properties

If one continously heats a particular magnet to high temperatures or long time or both, it loses it magnetism because the particles get excited and start forming no-magnetic arrangements.
The chemical properties of an element are determined by the number of electrons, which is determined by the number of protons. Isotopes vary in the number of neutrons in an atom of the same element (same number of protons). Since neutrons do not influence the number of protons or electrons, they do not affect chemical properties.
