Based on illustrations of magnetic field lines, where could an object be placed so it would not experience a magnetic force? halfway between the like poles of two magnets, because the field lines bend away and do not enter this area
halfway between the opposite poles of two magnets, because the field lines are the closest together
above the middle of a bar magnet, because the magnetic field lines are only found around the sides of the magnet
above a pole of a bar magnet, because the magnetic field lines either go in or go out at the end

since you're a real machine, your ama is always less than your ima, because you can never totally eliminate friction.

your answer is c! hope this : )

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
