could I use this device to measure magnetic fields in my home? I have some concern regarding the power lines nearby.

However, I'm certain the magnetic fields from nearby power lines are nothing to worry about unless they are literally running through your home. My suspicion is that you'll find the magnetic fields produced by essentially any electronic device in your house will be stronger

Will it tell you where North and South poles are?

Yes it indicates N or S when measuring
