The diagram illustrates the magnetic field surrounding a solenoid through which an electric current flows. What effect does increasing the current have on the magnetic field strength and on the spacing between the field lines?
- Astrength: decreases, distance between field lines: decreases
- Bstrength: decreases, distance between field lines: increases
- Cstrength: increases, distance between field lines: decreases
- Dstrength: increases, distance between field lines: increases
