By electitc field, i do not mean the magnetic field produced by a current carrying wire, but rather between charged particles. If a compass is placed between the electric field, will the compass needle delfect or will it just continue pointing in the initial direction?

If there doesn't exist magnetic field, then the needle will not be affected, will it? So just static charges I think won't move the needle, for they provide electric field only.

E field might induce surface charge on the needle. Don't know if you are meant to consider that possibility.

Right...I really forgot this situation. However if he emphasize the "electric field" not the "charge," I think the answer is still the same?

As far as motor action, magnetic force is much stronger than electrostatic force unless you are dealing with high voltages.
