No. If you have phase 1, 2, 3 (in that order), and phase 1 is the highest voltage at the instant a switching event occurs (causing a power surge), the surge voltage will be highest in phase 1. For polarity to change, you would need phase 2 to instantaneously change to greater than 1, which will not happen.
Permanent magnet field motors. With a these motors, a permanent magnet is used to replace the field coil. DC power is connected via the brushes, to the armature only. Reversing the polarity, will cause the motor to reverse its direction of rotation. It is very common to use a switch to intentionally reverse to the polarity, to allow reversal of the motor if desired.
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.
the power leads were wired wrong
You slowly decrease the power of the electromagnets.
No. Motors can be run in either direction, clockwise or counter clockwise. However, mechanically spinning an electric motor will generate electric power.

The case of reverse polarity would only happen on a DC system. As to would it cause equipment to run when switched off, no, if the switch opens the equipment's power supply completely the device will not operate.

There is a test swich which will change the polarity of the sensors........
A reversal of polarity in a 12-volt motor can occur if the wiring connections are switched or if a DPDT (double pole, double throw) switch is used to change the direction of current flow through the motor. It can also happen if a control circuit such as an H-bridge is used to control the motor direction.
if the power wires for the motor happen to be hooked up backwords
Only if it is a battery power tool and you fit the battery in reverse.
Normal polarity is for the power to normally go from positive to negative, reverse polartity is to change the positive to a negative and the negative to a positive so the power goes the other way.
Reverse polarity means connecting a power source, or polarised componenet, with the positive and negative poles the wrong way round. If the positive and negative supply is connected the wrong way round in electronic devices, it usually causes damage, because semiconductors are sensitive to polarity. Sometimes protection is provided, so that reverse polarity stops the device from working without causing damage. Connecting a diode (or rectifier) in reverse, will block the flow of current, without causing damage and is useful in protecting circuits from reverse polarity. In some consumer electronics (especially CB Radios) the power input has a recitifier across the 12v supply. If it is wired correctly, the rectifier is in reverse polarity, does not conduct and allows the radio to work. If you reverse the polarity of the power supply, the rectifier is now in full conduction, across the supply, causing a dead short. This shunts any power away from the radio and blows the fuse in the line, thus protecting it.
A: A stepper motor does it not start and spins but rather move to the next position according to the polarity of the power applied
Requires further diagnosis. You'll have take out the interior door panel and test the connection at the motor to see if power is getting to it. With the switch not engaged, there'll be no power. With the switch engaged, there'll be power, but the polarity for up is reverse from when the switch is in the down position.
When a magnet's polarity is reversed, the changing magnetic lines of force cutting across wiring induces a voltage in them. This principle is used primarily in motors. Or perhaps this refers to applying DC power to a device in reverse polarity by mistake. If the device is well designed, it will have a safety diode in the power input area to prevent damage, but if the diode is not present, reversing the power polarity will probably destroy every semiconductor junction in it.
