= Charged particle
{wiki}
A <charged particle> carries nonzero <electric charge> and couples to an <electromagnetic field>. For a classical point particle, the <Lorentz force> is $\mathbf F=q(\mathbf E+\mathbf v\times\mathbf B)$ in <SI>, distinguishing electric <acceleration> from velocity-dependent magnetic deflection.
An <electron>, a <proton> and an <ion> are examples with different masses and charge-to-mass ratios. A <magnetic field> can bend their tracks in a <particle detector>, while <ionization> along the path makes them observable in a <cloud chamber> or <bubble chamber>. A neutral particle can still interact electromagnetically through internal structure or moments; zero net charge does not imply total electromagnetic invisibility.
