The adjustment that would most likely result in a reduction of the magnetic field strength of a solenoid is:
**Lowering the current while reducing the number of coils.**
This is because both reducing the current and reducing the number of coils would decrease the magnetic field strength, as the magnetic field strength in a solenoid is directly proportional to both the current flowing through the coils and the number of turns (coils) of the wire.
**Lowering the current while reducing the number of coils.**
This is because both reducing the current and reducing the number of coils would decrease the magnetic field strength, as the magnetic field strength in a solenoid is directly proportional to both the current flowing through the coils and the number of turns (coils) of the wire.
