1. If the electron microscope were shooting a beam of protons instead of electrons at the same velocity, why would the effect of the external field deflect protons less but in the opposite direction?

2.  The lan considers installing a wire that will carry a large enough current to make a magnetic field that cancels the interfering field at the target. Why would would it be possible for the field of the wire to cancel the interfering field along the z or y axis, but not the x axis?

3. Suppose the wire is planned to pass the target at 3m from the target. safety considerations need them to have it 6m away. Why would they have to use twice as much wire rather than four times as much?

4. They give up on the straight wire and now construct a coil using 20 turns of wire. They need to measure the current in the wire. Point a is the 5th turn and point b is the 6th turn. To measure the current, why do they cut the wire at point a and insert the ammeter?
