In a transformer during pulse ON the primary has electrons flowing from ground to positive while on the secondary they are entering the positive side of the secondary and going to ground forming a counter magnetic field. During pulse of the voltage reverts but in the primary the electrons still going in the same direction while at the secondary they change direction and also the magnetic field being now the same magnetic field as the primary.
Electrons are made of electromagnetic mater but why during the rise of the magnetic field they flow in different directions?
The magnetic force is transversally received by the electron, this mean that if we were to use a magnetic field to stop the electrons they should cross a magnetic field?
