Torque (article) Khan Academy

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? WebThe magnetic field made by a current in a straight wire curls around the wire in a ring.

WebMay 12, 2016 · I know that if a current was flowing through this ring, the torque exerted by a magnetic field would be given by I ( A ^ × B ^). Where I is the current flowing in the circuit, A is the area of the coil and B is the magnetic field. As I understand, a current is just a flow of charge, or in other words, changing charge. WebThe formula used is, τ = m × B = m B sinθ. Where m- magnetic moment and B- magnetic field are applied. When a current loop is said to be placed in a magnetic field, it is believed …

WebThe torque about this axis is: τ = F (a/2) + F (a/2) = Fa = IabB. ab is the area of the loop, so the torque is, in this case, τ = IAB. This is actually the maximum possible torque, when the field is in the plane of the loop. When the field is perpendicular to the loop the torque is zero. In general, the torque is given by: τ = IA × B Web𝜏 = torque (Nm) r = distance from center to line of action (m) Positive and Negative Torques Torques that occur in a counter clockwise direction are positive torques. Alternatively, torques that occur in the clockwise direction are negative torques. So what happens if your hand points in or out of the paper?

WebAug 21, 2024 · Magnetorquers (also known as magnetic torquers or torque rods) are used in small satellites to provide attitude control – maintaining the satellite’s orientation with respect to an inertial frame.. Magnetorquers produce a magnetic field around the satellite which interacts with the Earth’s own magnetic field, thus producing a torque on the satellite.
