How do you know if there is magnetic torque

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 …
