1. The problem statement, all variables and given/known data An alien civilization has crossed the galaxy to invade the Earth and enslave humanity, again. Their attacks have been successful so far because their assault troops are equipped with handheld weapons that project beams of charged particles (protons & electrons) at very high speeds, able to melt or vaporize solid objects on contact. To counter this frightening weapon, the Earth Defense Force has developed a super-strength bar magnet that can be attached to a human soldier's helmet or weapon, so that its magnetic field will stop or deflect the charged particles. in order for the magnet to counter a beam being fired at a soldier from directly in front, how should the bar magnet be oriented? Should the N or the S pole be pointing directly forward? Or should it be vertical, and if so, should the N or the S pole point upward? Or won't this work at all? 2. Relevant equations 3. The attempt at a solution The magnet will help save the soldiers and the planet. By holding the magnet in front in a horizontal position. North and South from left to right in front of him holding it on his head where the magnet would be parallel to the gorund. This will create a magnetic field from the magnet spreading that will protect the soldier better. If he were to hold it vertically, the field wouldn't be protecting his lower body very well. What more can I say to this to help back my argument?
