If the magnetosphere of Earth disappeared

    Would this noticeably increase the radiation level on Earth?

    Or would the atmosphere easily stop the excess solar-wind particles which are now not being deflected away?

    The particles themselves for the most part would be absorbed by the atmosphere. However we would probably start to have a dramatic increase in amount of gas lost from the atmosphere thanks to the solar wind. (Though still an extremely small amount on our timescale)

    I don't think the magnetosphere protects vs photon radiation, such as gamma and x-rays, but I could be wrong.

    it indeed does not have any effect on electromagnetic radiation.

    So wrapping a giant loop of wire around the equator and hooking it to a battery to neutralize the earths magnetic field would not be on the list of evil genius plot ideas...

    I don't think we would have to worry about that anyways. :biggrin:
