Why does electromagnetic spectrum have the magnetic in its name?

Spectrum first: that's a range.
The range here is the range of the energies of photons (light quanta).
So we're talking about photons,
which are always moving--at the speed of light.
A moving photon can be thought of as two sine waves
stretched out in its direction of travel.
(The planes of the two waves are at right angles,
and they are ninety degrees out of phase.)
One of the waves represents (signed, i.e., plus and minus) electric field intensity;
the other, magnetic field intensity.

Why is light in the electromagnetic spectrum Is light a type of electromagnetic radiation But how does that work Light is not magnetic or is it?
Part of the electromagnetic spectrum can be detected by eye, and we call that bit "light". The thing about electromagnetic radiation is that a varying magnetic field causes a (varying) electric field (that's how power stations make electric current) and a varying electric field causes a (varying) magnetic field. So electromagnetic radiation is what you get when a varying electric field creates a varying magnetic field which in turn contributes the varying electric field. The whole thing then appears as bundled varying electric and magnetic field wave system which propagates at the velocity of light, That is why it is called electromagnetic. There are no magnetic poles or electric charges in it, and it can travel through a vacuum.
What does a electromagnetic spectrum contain of?

the energy that makes the electromagnetic spectrum is electromagnetic radiation
What is a field in the electromagnetic spectrum?
There are electric fields and magnetic fields. If those change over time, the changes may propagate at the speed of light - that's called an electromagnetic wave.
The various types of electromagnetic radiation are distinguished from each other by their?
Electromagnetic waves are classified according to their wavelength and frequency and this classification is called electromagnetic spectrum.
