A straight solenoid of length 50 cm has 1000 turns per metre and mean cross-sectional area of `2 xx 10^(-4) m^(2)` . It is placed with its axis of `30^(@)` with uniform magnetic field of 0.32 T . Find the torque acting on the solenoid when a current of 2 ampere is passed through it .

Text Solution

Verified by Experts

Torque of solenoid is given by
`tau = MB sin theta `
`= (NA) B sin theta`
` = 500 xx 2xx xx 10 ^(-4) 0.32 xx (1)/(2)`
= ` 0.032 Nm`
