To decrease the magnetic field strength produced by an electric coil, the most appropriate choice from the options provided is:
**reducing the voltage of electric current in the coil.**
Reducing the voltage will decrease the current flowing through the coil, which, in turn, reduces the magnetic field strength. The other options would either have no effect or would increase the magnetic field strength.
**reducing the voltage of electric current in the coil.**
Reducing the voltage will decrease the current flowing through the coil, which, in turn, reduces the magnetic field strength. The other options would either have no effect or would increase the magnetic field strength.
