    The SCR would be more effective and probably cheaper, too.

    Here is an example circuit:

    I have built some version of this circuit several times in the past. It works great.

    Your 'coil' will be in place of RL in the circuit.

    With this circuit, you can keep adding SCRs in the chain and use even higher voltages (which will provide more current for the coil).

    This is the kind of transformer (T1) they are talking about:

    Check Digikey.com to see if they carry one of these models. If not, Google it to find out who carries it.
