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.
If both the field and armature currents in a motor are reversed, the direction of the magnetic field and the armature's rotation will also reverse, resulting in no change in the overall motion of the motor. The torque produced will still act in the same direction as before, maintaining the motor's operational characteristics. However, this may cause issues in certain applications where the direction of rotation is critical. Overall, the motor will continue to function but with a reversed magnetic orientation.
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.
If the orientation of both diodes in a double-level slicer is reversed, the circuit will not function as intended. Diodes only allow current to flow in one direction, so reversing them will block the current flow, preventing the circuit from operating correctly. This would result in the output levels not being sliced as designed, rendering the circuit ineffective.
as direction of current reverses it is shown in form of positive and negative cycles
If you mean what would happen if you connected a DC device backwards, there could be one or two things happen depending on that the device is. If it was a DC motor it would operate in the opposite direction. If it was an electronic device it could burn out some components. Or with today's electronics nothing would happen. Up until a few years ago polarity to electronic devices was crucial that it be connected correctly. In today's electronics a bypass diode is inserted into the voltage supply line that will block the current flow if the connection is reversed. This one little addition to the circuit supply has saved the frying of many electronic components.
If the direction of the current in an electromagnet is reversed, the direction of the magnetic field surrounding the electromagnet will also reverse. This change in direction will affect the polarity of the electromagnet, causing its north and south poles to switch.
Then the resultant vector is reversed.
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.
If both the field and armature currents in a motor are reversed, the direction of the magnetic field and the armature's rotation will also reverse, resulting in no change in the overall motion of the motor. The torque produced will still act in the same direction as before, maintaining the motor's operational characteristics. However, this may cause issues in certain applications where the direction of rotation is critical. Overall, the motor will continue to function but with a reversed magnetic orientation.
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".
Nothing just that it does not move to that direction

When reverse the direction of a seperately excited DC generator,only polarities has been reversed,i.e., (+) becomes (-) and (-) become (+).
If the orientation of both diodes in a double-level slicer is reversed, the circuit will not function as intended. Diodes only allow current to flow in one direction, so reversing them will block the current flow, preventing the circuit from operating correctly. This would result in the output levels not being sliced as designed, rendering the circuit ineffective.
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.
If dc current is passed through a single coil, it is going to remain constant.
