Lorentz force equations, power factor in LCR circuits at resonance, and magnetic susceptibility changes in ferromagnetic materials. Modern Physics:

The statement "relative permittivity of water is 81" indicates that the force between two charges in water is 1/81 times the force between the same charges in a vacuum. Lorentz Force: The force acting on a charge moving with velocity in a magnetic field Bbold cap B is given by the vector equation Isc 2009 Physics Paper Solved
