We know that it''s neither a battery nor a magnetic field, for a battery does not have to be present in a circuit where current is induced, and magnetic fields never do work on moving charges. The answer is that the source …
How a battery works
When we connect an almost flat battery to an external electricity source, and send energy back in to the battery, it reverses the chemical reaction that occurred during discharge. This sends the positive ions released from the anode into the electrolyte back to the anode, and the electrons that the cathode took in also back to the anode.
Why Do Moving Charges Create a Magnetic Field? The Physics …
The formula given above also indicates that a magnetic field is only produced if the charge is moving.But, you could ask whether it''s possible for a stationary charge to also produce a magnetic field.

Electric Field Calculator
An electric field is a field that exerts a force on charges – attracting or repelling them. Moreover, every single charge generates its own electric field. That''s why, for example, two electrons with the elementary charge e = 1.6 × 1 0 − 19 C e = 1.6 times 10^{-19} text{C} e = 1.6 × 1 0 − 19 C repel each other. ...
