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? WebA magnetic field exerts a torque which tries to align the normal vector of a loop of current with the magnetic field. torque = (# turns) * (current) * (loop area) * (mag field) * sin … crypto tokens by market cap

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? WebEssentially, what happens when you turn on the magnetorquer is that there is a torque applied to move the spacecraft to line up with the magnetic field vector.

http://spiff.rit.edu/classes/phys213/lectures/amp/amp_long.html WebAny force that is not parallel to the radial vector will have a component that is perpendicular to the radial vector. This perpendicular force will cause the material to want to rotate in the direction of the perpendicular component. This is called a moment of force or torque.

WebApr 10, 2016 · τ = m × B In classical mechanics, the torque is given as τ = r × F The force is derivable from a potential energy V, i.e. F = − ∇ V; you can write the torque as τ = − r × ∇ V. The dynamics of an object carrying an electric current is governed by the Lorentz force, a velocity-dependent force that cannot be derived from a potential energy function
