Question

why EMF is induced before current in the experiment dobe by faraday ?​

Answer 1

Answer:

Faraday's Apparatus: This is Faraday's apparatus for demonstrating that a magnetic field can produce a current. A change in the field produced by the top coil induces an EMF and, hence, a current in the bottom coil. When the switch is opened and closed, the galvanometer registers currents in opposite directions.
