And I mean what is happening on an atomic level that is not happening with DC so that induction can occur? I’ve been doing a lot of reading to wrap my head around it but I can’t seem to get an answer that explains what is happening throughly, just a lot of “just because”. What is going on with the electrons that allows them to transfer over to the second coil that does not occur with DC?

Current creates a magnetic field. Constant current creates a constant magnetic field. Changing currents create a changing magnetic field.
Constant magnetic fields don’t create current. Changing magnetic fields do create currents
If you apply DC to the primary side of a transformer the current will ramp up in the primary side and will increase the magnetic field in the core and the change in the field creates a voltage on the secondary which pushes current along. Then the magnetic core saturates, the field is no longer changing so there’s no voltage/current on the output, and there’s no inductance to resist current on the primary so it’s just a giant resistor an promptly lights on fire
For AC the current is constantly increasing and decreasing so you stay in that starting time frame so if passes energy across during all of its operation
It’s important to not that electrons aren’t transferring, their energy is.
Think of a transformer like a seesaw. If you hook one end(secondary) up to and old timey water pump then just place a big rock on the other side (DC) then you just get one pump and nothing interesting happens. If you instead get your friend to grab the end of the seesaw and push it up and down repeatedly then the pump will work
We’re using the magnetic field as the board on the seesaw to transfer the energy from the changing electric field on one side into a changing electric field on the other side
