Moving charges make magnetic fields Magnetic fields affect moving charges Electric and magnetic fields depend on reference frame Change reference frame: magnetic field is converted into electric E x ' = E x E y ' = E y ! vB z ( ) 1 ! v 2 / c 2 E z ' = E z + vB y ( ) 1 ! v 2 / c 2 Time varying magnetic field can produce electric field! (magnetic induction) Electric and Magnetic Fields Electric and magnetic fields are interconnected
