Question 116: Electromagnetic Induction

Question

Two coaxial solenoids of different radius carry current $I$ in the same direction. $\overrightarrow {{F_1}} $ be the magnetic force on the inner solenoid due to the outer one and $\overrightarrow {{F_2}} $ be the magnetic force on the outer solenoid due to the inner one. Then :

Accepted Answer

$\mathop {F{}_1}\limits^ 	o   = \mathop {F{}_2}\limits^ 	o   = 0$
because of action and reaction pair

Answer

$\overrightarrow {{F_1}} $  is radially in wards and $\overrightarrow {{F_2}}  = 0$

Answer

$\overrightarrow {{F_1}} $  is radially outwards and $\overrightarrow {{F_2}}  = 0$

Answer

$\overrightarrow {{F_1}}  = \overrightarrow {{F_2}}  = 0$

Answer

$\overrightarrow {{F_1}} $ is radially inwards and $\overrightarrow {{F_2}} $ is radially outards
