Find the magnitude of Torque |T| when a Force vector of magnitude |F| = 38 N, and a radius vector of |r| = 9 m act at a point where the angle between the Force and radius vectors is: angle = θ = 49 degrees.

One solenoid is inside the other solenoid. Both solenoids have length L and N turns. The radius of the inner solenoid is 2R and the radius of the outer solenoid is 3R. The inner solenoid carries current 41 and the outer solenoid carries current l in opposite directions as shown. What is the magnetic field at a distance R from the central axis? Both solenoids are long and thin, i.e., L >> R. > +x

A wire loop that is carrying a current I is shown in the figure. The direction of the current is also indicated in the figure. This loop is inside a magnetic field whose flux density is given as B = -5x + y The forces acting on this loop will try to ◆ axis (Note: Be careful about the sign of the axis as it will indicate the rotation direction). ◆ it. And the net torque on the loop will try to rotate it along the I N X
