    This is probably a silly question, but as it is possible to polarise the electric field vector of light waves, is it possible to polarise the magnetic field vector of electromagnetic radiation? In all my notes it says that polarisation is only concerned with the electric field, but how come it doesn't involve the magnetic field?

    Thanks

    we havent actually done or mentioned this at all, but wouldnt polarising the electric field sort of automatically polarise the magnetic field?

    i may be compleeeeeeeeeeeeeetely wrong here though!

    of course it would since they are at right angles to each other.

    I agree as that seems logical, it's just in the notes we were given on Polarisation it says "Polarisation is only concerned with the electric field vector" which implies to me that magnetic fields are not polarisable, but then that didn't make sense considering electromagnetic radiation consists of the interaction between electric fields and magnetic fields at right angles to one another! :s
