In that case, the magnetic field will also be reversed.
If you change the direction of current in an electromagnet, (which by the way is just a coil of wire) then the direction of the magnetic field will also be reversed: That is to say, what was north is now south. If you want more info. look up "the left hand rule".
If you reverse the polarity in a parallel circuit, the components will still function but the direction of current flow through each component will be reversed. This could lead to a change in the behavior of any polarized components in the circuit, such as diodes or electrolytic capacitors. It is important to ensure that the components can handle the reversed polarity to prevent damage.
Conventional current is the effective direction of positive charge. When in a metal the negative charged electrons are moving in one direction, the conventional positive current is in the other direction.
The needle of the compass will align itself with the magnetic field produced by the electromagnet due to the flow of electric current in the coil. The compass needle will point in the direction of the magnetic field lines, which are generated by the current passing through the coil of the electromagnet.
Lateral inversion is caused because the distance of the image behind the surface of a (flat) mirror is same as the distance that the object is in front of the mirror. So the image is reversed from "front to back". The image often APPEARS to be reversed sideways instead of front to back. "Lateral" means sideways.
The idea is that the magnetic field of the device reacts with the external magnetic field. If the current is reversed, the magnetic field would also be reversed, and the reading would be the opposite.
Then the resultant vector is reversed.

Nothing just that it does not move to that direction
No changes will occur by wiring a 110 volt motor in reverse polarity, rotation will always be the same. Some single phase motors are designed to be reversed ,but that is a function of the relationship of start windings and capacitors and requires some wiring changes in a motor junction box or an end terminal housing, not by just changing the incoming power.
When reverse the direction of a seperately excited DC generator,only polarities has been reversed,i.e., (+) becomes (-) and (-) become (+).
Direction of the magnetic lines too would get changed
it will work as a rectifier . because the AC current to be rectified will not be effected by this change. the out put DC polarity will be changed.
as direction of current reverses it is shown in form of positive and negative cycles
if ac changes direction then how current happen to flow
as we know that in reverse bias condition no current is produced and if it produced by the minority charge carrier then also the current produced is in very less amount so u can say that emitter current will reduced to large extend as compare to emitter current in forward bias condition
