$\oiint \vec B \cdot \vec d A = 0$, flux is 0 so the magnetic charge does not exist

Magnetic Force

$\vec F _B = q \vec v \times \vec B$, units in Tesla

• Orbital angular momentum and spin produce magnetic moment (quantum perpsective)
• Magnetic field arises from charges moving
• If the charge experiences no force, $\vec F _ B = 0$, there is no charge
• If charge moves perpendicular to the magnetic field, the force is maximum
• If the charge moves at an angle that is not 90 or 0, the charge experiences a force between 0 and $qvB$
  • V is the velocity of a charged particle, B is the magnetic field

Lorentz Force: $F = \vec F _E + \vec F _B = q \vec E + q \vec v \times \vec B$

Calculating the Magnetic Field of Current Carrying Wire

• RHR tells you which way the magnetic field is going
