Question

What did the experiments of Michael Faraday and Joseph Henry around 1830 demonstrate?

पर्याय

• Electric currents were induced only in stationary coils with constant magnetic flux.

• Changing magnetic fields prevented current in closed coils.

• Electric currents were induced only when a coil was an open circuit.

• Electric currents were induced in closed coils subjected to changing magnetic fields.

Answer 1

Faraday and Henry demonstrated induction in closed coils exposed to changing magnetic fields. The changing field changes the magnetic flux passing through a coil.
