Magnetostatics

Magnetostatics describes the effects of unchanging magnetic fields. Use Wolfram|Alpha's collection of formulas to compute the magnetic fields for and their effects on different objects. Calculate the Lorentz force, the magnetic field of a solenoid or the magnetic flux density of a Helmholtz coil. Examine the equations associated with different magnetized objects.
