WebMay 4, 2024 · the torque is τ = p x B where p x B is the vector cross product (= the magnitude of p and B times the sine of the included angle ), and B is the magnetic field inside the solenoid. If you know the moment of inertia of the magnet, you can calculate the oscillation period of the magnet in the solenoid. WebMay 9, 2024 · FD = I( + ˆxL) × (ˆxB0) = 0. Thus, the force exerted on the current loop by the impressed magnetic field will lead to rotation in the + ˆϕ direction. We calculate the associated torque T as. T = TA + TB + TC + TD. where TA, TB, TC, and TD are the torques associated with segments A, B, C, and D, respectively.

http://physics.bu.edu/~duffy/semester2/c13_torque.html WebA torque is a vector quantity which means that it has both a magnitude (size) and a direction associated with it. If the size and direction of the torques acting on an object are exactly balanced, then there is no net torque acting on the object and the object is said to be in equilibrium.

Torque on a current carrying loop in non-uniform magnetic field

WebThe direction is perpendicular to both the radius from the axis and to the force. It is conventional to choose it in the right hand rule direction along the axis of rotation. The torque is in the direction of the angular velocity … WebDec 25, 2024 · The torque (tendency of an object to rotate) depends on three different factors: τ = rFsin (θ) where: r is the lever arm - the distance between the pivot point and the point of force application; F is the force acting on the object; θ is the angle between the force vector and lever arm. Typically, it is equal to 90°; and τ is the torque.
