Define magnetic force vector $\vec{F}$

The force exerted on a current-carrying wire or moving charge by a magnetic field; a vector quantity.

Define current $I$ in the context of magnetic forces on wires.

The rate of flow of electric charge through the wire, measured in Amperes (A).

Define length vector $\vec{L}$ of a wire in a magnetic field.

A vector representing the length of the wire segment within the magnetic field; its direction is the same as the current.

Define magnetic field vector $\vec{B}$ .

A vector field that describes the magnetic influence of electric currents and magnetic materials.

Define torque $\tau$ on a current loop.

A rotational force that causes the loop to rotate in a magnetic field.

Define permeability of free space $\mu_0$ .

A physical constant that relates the magnetic field to the electric current that produces it. $\mu_0 = 4\pi \times 10^{-7} T \cdot m/A$

Define magnetic force vector $\vec{F}$

The force exerted on a current-carrying wire or moving charge due to a magnetic field.
