Two coaxial solenoids of different radius carry current I in the same direction. `vec(F_1)` be the magnetic force on the inner solenoid due to the outer one and `vec(F_2)` be the magnetic force on the outer solenide due to the inner one. Then

A

`vec(F_1)` is radially inward and `vec(F_2)`

B

`vec(F_1)` is radially outwards and `vec(F_2)=0`

C

`vec(F_1)=vec(F_2)=0`

D

`vec(F_1)` is radially inwards and `vec(F_2)` is radially outwards

Text Solution

Verified by Experts

The correct Answer is:
C
(c) `vec(F_1)=vec(F_2)=0`
beacuse of action and reaction pair .

Two long coaxial insulated solenoids, S_1 and S_2 of equal lengths are wound one over the other as shown in the figure. A steady current "I" flow through the inner solenoid S_1 to the other end B, which is connected to the outer solenoid S_2 through which the same current "I" flows inthe opposite direction so as to come out at end A. If n_1 and n_2 are the number of turns per unit length, find the magnitude and direction of the net magnetic field at a point (i) inside on the axis and (ii) outside the combined system.
