INDUCTION HEATING/MELTING If an AC current is fed through a coil, the electromagnetic field that is  produced  is  constantly  changing.  This  changing  magnetic  field  induces  electrical current (AC) in another circuit that is held close . This  induced  secondary  current  can  be  utilized  to  generate  heat  in  the  circuit of the second conductor by exploring the electrical losses due to the  current. These losses are due to Hysterises and Eddy current. 3

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
