Magnetic Direction Finding
I can't see why you would not be able to use a spark gap. I used a piezo electronic lighter to test an experimental antenna. You have to be close to the antenna, within 12 to 24 inches.
Also keep in mind that ferrites and loop have nulls in certain directions. For example, a ferrite's null is in the direction of the core.

Have fun experimenting.
