In his first experience, Faraday used two coils and an iron core. One of the coils was connected to a milliammeter, the other to a switch. What did Faraday observe? Induced currents were only detected when the circuit-breaker was closed and opened, they were equal in intensity but opposite in verse. The milliammeter always detected an induced current, as long as the switch was closed There was no induced electric current when the ferrous core was removed Induced currents were only detected when the circuit-breaker was closed and opened they were equal in intensity and direction
