Two coaxial solenoids of different radii carry current I in the same direction. Let F 1 → be the magnetic force on the inner solenoid due to the outer one and F 2 → be the magnetic force on the outer solenoid due to the inner one. Then:

F 1 → is radially outwards and F 2 → = 0

F 1 → is radially inwards and F 2 → is radially outwards

F 1 → is radially inwards and F 2 → = 0
