Question

A square shaped plane coil of area 100 cm2 of 200 turns carries a
steady current of 5A It is placed in a uniform magnetic field of 0
2 T acting perpendicular to the plane of the coil Calculate the
torque on the coil when its plane makes an angle of 60° with
the direction of the field In which orientation will the coil be in
stable equilibrium ?

Dear
Student,
Please find below the solution
to the asked query:
Torque acting on the coil:τ=BIAN cosθ =0
2×5×100×10-4×200×cos60o =1 N·mOrientation of stable equilibrium:Here, torque should be equal to zero
Plane of the coil is perpendicular to magnetic field, θ=90o
Hope this information will
clear your doubts about Torque on current carrying
coil
