Hi,
I've been trying to figure several simple things about electric and magnetic fields, their relationship with current.
If you could please help me understanding this, it would be really helpful.
From what I've read these were presented as natural laws:
1. Changing magnetic field induces current in a conductor, causes electrons to move in other words.
2. Changing magnetic field creates changing electric field.
3. Changing electric field creates changing magnetic field.
Got several questions. One question is, does changing magnetic field induce current (move electrons) by first creating changing electric field ? I am trying to figure out if there are 2 or 3 steps in the process.
(1)Changing magnetic field -> (2)changing electric field -> (3)moving electrons
or is it
(1)Changing magnetic field -> (2)moving electrons ?
I can think of first option with 3 steps (changing magnetic field->electric field->current) as electric field exerting forces on charges (electrons), hence their movement. On the other hand if there are only 2 steps (changing magnetic field->current), how does that work...because for charges to move there must be an electric field, what causes charges to move otherwise ? individual magnetic fields of electrons ?
