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. 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 iphone bentgateWebAny 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. iphone best buy trade in deals
