WebThe magnetic field made by a current in a straight wire curls around the wire in a ring. You can find it by pointing your right thumb in the direction of the current in the wire and curling your fingers. Your fingers will be curled in the same direction as the magnetic field … 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. Like a compass needle, the magnet will line up with the north pole …

WebTorque is inherently a vector quantity. Part of the torque calculation is the determination of direction. The direction is perpendicular to both the radius from the axis and to the force. It is conventional to choose it in the right … 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. Using a calculation analogous to that found in Capacitance for an electric dipole, the potential energy of a magnetic dipole is pop on youtube tv
2.3: Torque Induced by a Magnetic Field - Engineering …
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. 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 … 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. share with onedrive
