i am using electromagnetic sensor which is 24volts. in that i only have the connections for power voltage(positive) and the signal. when i am trying to power it with my stm32f411re nucleo board i can see that the power isn't sufficient. so can i use a 24volts power supply to that and the negative to the stm32f411re nucleo board ground. 
so i was thinking the connections would be like,
power supply positive to the sensor positive, signal to the stm32 nucleo board. power supply negative to the ground of the stm32 board.  would these connections make sense, or would it fry my board?
is there any quick connections to power the sensor with 24volts. quickest answer is much appreciated. thank you in advance.

What do you mean by that?

The magnet is either on or off - if you also want it to move, that's a whole extra part of your project

 i can see the CPU out pin, can you show or name where is it in the board. 

That's up to you to decide, and write your software accordingly.

I think you need to take a few steps back, and start with some basics
