A unit N- pole is placed on the axis of a circular coil carrying current in anti - clockwise direction. It experiences a force

A circular loop with N turns has radius r . It lies in the x-y plane carrying current I in the anti-clockwise direction . If the magnetic field in the region is vecB = B_0hati , then find the torque (vecr) acting on the loop .

Two insulated circular loop "A" and "B" of radius ' "a" ' carrying a current of ' "I" ' in the anti clockwise direction as shown in the figure.The magnitude of the magnetic induction at the centre will be

A particle is describing uniform circular motion in the anti-clockwise sense such that its time period of revolution is T. At t = 0 the particle is observed to be at A. If theta_1 be the angle between acceleration vector at t=T/4 and average velocity vector in the time interval 0 to T/4 and theta_2 be the angle between acceleration vector at t= T/4 and the vector representing change in velocity in the time interval 0 to T/4, then :

A person walks 2sqrt(2) units away from origin in south west direction (S45^(@)W) to reach A , then walks sqrt(2) units in south east direction (S45^(@)E) to reach B . From B he travel is 4 units horizontally towards east to reach C . Then he travels along a circular path with centre at origin through an angle of 2pi//3 in anti-clockwise direction to reach his destination D . Position of D in argand plane is ( w is an imaginary cube root of unity)

Let the complex number Z represents C in argand plane. then arg(Z)=

An electron in the ground state of hydrogen atom is revolving in anti-clockwise direction in the circular orbit of radius R as shown in figure. Obtain an expression for the orbital magnetic dipole moment of the electron.
