In the tiresome, too-long movie "Mr. Turner" about the painter JMW Turner, there is a bizarre scene in which Mrs Mary Somerville tries to demonstrate that the ultraviolet portion of the spectrum will magnetize a steel needle. "In 1826 her paper, The Magnetic Properties of the Violet Rays of the Solar Spectrum ..." http://blogs.rmg.co.uk/rog/2014/10/29/mr-turner-mrs-somerville/ Of course, this idea is BS, as she eventually realized: "Mary later retracted her claim that violet rays could magnetise a steel needle when further experiments failed to give the same result" I wasn't able to follow all of the goings-on in the movie, but I don't think Mary's retraction of this claim made it into the movie. I'm afraid that a whole generation of non-scientists who watched this movie will now swear that ultraviolet light magnetizes steel needles. Hopefully, the movie will inspire a number of high school science fairs to investigate this non-phenomenon.
