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. At what condition torque is zero? tso letterhead

WebUsing our right hand rule, where the current travels downwards and the magnetic field travels left, we can determine the force to be into the page. For the right side, wherein the current travels upwards, we can use the right hand rule to determine the force on that chunk of wire is out of the page. WebMagnetic Torques and Amp's Law. A magnetic field exerts a force on a straight wire carrying current; it exerts a torque on a loop of wire carrying current. Torque causes an object to spin around a fixed axis. Each loop of current has a direction associated with it: its normal vector is perpendicular to the loop, in the direction given by the ... tso lead

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. WebIn terms of the magnetic dipole moment, the torque on a current loop due to a uniform magnetic field can be written simply as (8.5.9) This equation holds for a current loop in a two-dimensional plane of arbitrary shape.
