A current-carrying coil experiences a turning effect when it is placed in a magnetic field. Which row gives two changes to the coil that each result in a greater turning effect?
1 )
number of turns on the coil: decreases / current in the coil: decreases
2 )
number of turns on the coil: decreases / current in the coil: increases
3 )
number of turns on the coil: increases / current in the coil: decreases
number of turns on the coil: increases / current in the coil: increases
