How do attracting and repelling forces between magnets and elctromagnets make a motor turn?

The elctromagnet has a phase difference between it and the rotor magnet. The electromagnet leads the rotor and attracts one side and repels the opposite side. This torques makes the motor turn.

How is Law of electric charge related to electric motor?
An electric motor is made up of magnets .. some electric induced magnets , some permanent magnets . the electric magnets are arranged so that when the power is turned on they activate in a series of pulsing magnets.. this pulsing causes the magnets in the core and the magnets in the body of the motor to repel and attract as magnets will do .. this repelling and attracting causes the magnets to try and chase each other around .. this action is turning the core of the motor and producing the rotating action expected from an electric motor
Why can't a perpetual motion machine be made from magnets repelling each other?
The two magnets would push each other apart until friction takes-over, then there'd be no more motion.
Does a magnets pull force match its push force?
Yes. I used a wheel and placed magnets all around it, then I spun the wheel and placed another magnet in front of the wheel and thought that the wheel would keep spinning due to the magnets repelling each other but it didn't work.
What happens when you break a magnet in half?
The north and south poles would remain. The two new pieces would now have a north and a south. The magnet would still be magnetic, with its like poles repelling each other and its unlike poles attracting each other.
If you place a second object between two magnets?
If will decrease (if the object is bigger than than both magnets) the force acting between two magnets in mu times (where mu is magnetic constant for the object between magnets).
When two bar magnets bring together what can we observe?
You can observe them attracting or repelling each other.
If two magnets are attracted to one another and another two are repelling the two magnets that are being attracted can you move the 2 magnets by repelling it by the repelling magnet?
Yes. Just ensure the the like poles are facing each other. Like poles repel.The two magnets that are attracting are effectively one magnet.It would look like this:-([-magnet 1+]first pair attracting[-magnet 2+])++(+[magnet 1-]second pair repelling[-magnet 2+])+
Are repelling magnets stronger than attracting magnets?
No. The same two magnets can either repel each other or attract each other, depending on how you turn them. The force is the same either way.
Does north stick to north for magnets?
No. The north sides of two magnets do not stick together because they have the same polarity. The north and south sides of a magnet, however, do stick together because they are on opposite poles and, pertaining to magnets, opposites attract. actually if you push two repelling magnets together so they touch they will stick, without flipping, not entirely sure why they don't repel but it seems that the magnetic fields somehow overlap, so that within the repelling field there is a small of the attracting field, i know this isn't true of the attracting side because the magnets stick together regardless, but on the repelling side when they touch they will stick
Why does the magnet's north attracts north of another magnet?
The north sides of two magnets do not stick together because they have the same polarity. The north and south sides of a Does_north_stick_to_north_for_magnets, however, do stick together because they are on opposite poles and, pertaining to magnets, opposites attract.actually if you push two repelling magnets together so they touch they will stick, without flipping, not entirely sure why they don't repel but it seems that the magnetic fields somehow overlap, so that within the repelling field there is a small of the attracting field, i know this isn't true of the attracting side because the magnets stick together regardless, but on the repelling side when they touch they will stick It doesn't. A magnet's North will attract another magnet's South and vice versa
Why don't two magnets stick together?
Because in order for them to be magnetized - they must be polar opposites

What characteristic exists in magnets that does not exist in materials that lack magnetism?
The characteristic that exists in magnets but not in non-magnetic materials is the presence of magnetic domains, which are regions within the material where the atomic magnetic moments align in the same direction. This alignment leads to the overall magnetic behavior observed in magnets, such as attracting or repelling other magnetic materials.
What is the ability to attract metal things?
Magnetism in the name for metals attracting to each other. Magnets draw other metals and magnets to themselves. It is a powerful bond that can hold something in between the magnets and still hold a connection.
Why are magnets stored in attracting positions?
The simple answer is that it takes much less time and energy to store them in the attracting potions. If you tried to store magnets in non attracting positions they will attempt to push themselves away from each other or align them self to the attracting positions of the other magnets. If forced togeater in non attracting positions over time they could become demagnetized or the weaker ones will realign to the polarity of the strongest magnetic force.
What will happen when the magnetic field of two or more magnets overlap?
Refer to the link below to see an image of two attracting ball magnets.
