Phases in AC refer to the number of sine waves of alternating current used to generate the average voltage. In 2 phase, two opposing sine waves are overlapped to give the average voltage delivered, eg 240V in household supplies.
In 3 phase, three sine waves are overlapped to produce a more consistent average voltage.
I believe the term 'three pole' is used for the circuit breaker that is used in a three phase circuit. The number of poles is the number of current paths broken when the breaker trips or is switched off. If you look into a circuit breaker box, you might notice the breaker for the electric stove (range) is twice as wide and the breakers for lighting, etc. This because the lights operate on 120V (in the US) which is a single pole breaker, whereas the stove (range) needs 240V to power the 'burners' If you checked the power socket for the range, you should note each hot lead is 120V relative to ground but 240V relative to the other hot lead. This requires a double pole breaker to disconnect both hot leads. A three phase circuit requires all three hot leads be disconnected and this requires three poles. Three phase power is generally not used in residential installations.
In electrical terms, 3 pole is a description used for a type of switch of circuit interrupter. This type of switch is used on three phase applications where the three line voltages are all disconnected with one pull of the switch's handle. In electrical terms, 3 phase is defined as generation or use of a designed supply that uses three simultaneously separate alternating currents of the same voltage, but with phase voltages spaced at 120 degrees separation from one another.
No of flux line producing can be the difference. And we need improved external structures to get maximum out put voltage through 3pole than 4pole.

What is an acceptable difference in resistance between phases on a 3 phase motor?
The currents between legs of a three phase circuit should be within about 10% of each other.
What is the difference between a tpn mccb and a 4 pole mccb?
The difference between a tpn mccb and a 4 pole mccb is rather negligible. The only real difference is that a 4 pole mccb works a little bit faster and allows for a strong network connection. The connection with a 4 pole mccb is just a bit more reliable.
Why does a 3 phase motor turn slowly?
An induction motor relies on low-frequency currents induced in the rotor by the difference in speed between the rotor and the rotating magnetic field. At sychronous speed the induced current is zero therefore the torque is also zero.
What is the difference between a single phase compressor and a 3 phase compressor?
One uses single phase AC current (120/240), the other uses 3 phase AC current (most households will not have 3 phase in their home) One uses a 3 phase motor the other a single phase motor. 3 phase is usually used in industrial applications while single phase is used in home or small business apps.
Is there a difference between 3 pole and 3 phase?

What difference between using 4poles circuit breaker and using 3 single pole breakers?
3 pole would be for 3 phase, 4 pole would be 3 phase & neutral
Developed diagram of 3 phase 2 pole 24 slots induction motor?

Is 3 phase power and 3 pole power the same?
3 Phase power is supplied by a 3 pole supply like a breaker. So essentially yes.
3 pole circuit breakers?
3 pole circuit breakers are used for 3 phase lines
What is the phase difference between in two voltage phases in 3 phase distribution system?
The phase difference between any two live lines is 120 degrees, which allows them to peak in turn in the 360-degree cycle.
What is the difference between 4-pole changeover switch and 3-pole changeover switch?
4-pole changeover switch connects also the neutral wire. 3-pole changeover switch connects only the 3 live wires.
What is the difference between a 2- pronged cable and a 4 - pronged cable?
2 prong is a hot and neutral and a 4 prong is a 3 phase with a ground wire.3 pole 4 wire meaning 3 hots could be 240 volts or 480 volts

What is an acceptable difference in resistance between phases on a 3 phase motor?
The currents between legs of a three phase circuit should be within about 10% of each other.
