Torsion Balance

For measurement of small torques as required e.g. in experiments on Coulomb's law of electrostatics' and magnetostatics or when measuring the forces in homogeneous electric fields or the magnetic fields of straight and circular conductors as well as the force acting on a current-carrying loop in a magnetic field.
