Sounds ok. I was concerned if they were wired so that one side had the
+ terminal next to the head and the other side had the - terminal
likewise. That would be a rather strong field to place the brain
inside of.

As long as they are either shielded or wired with the same polarity
next to the head, there should be no problem.
