Our magnetic field protects us from the solar winds (charged plasma expelled from the sun into space). They cause the Northern Lights. If they hits us straight on, we'd all die from the radiation. And they would mess with our electronic equipment.

Yes, it would. Without the magnetic field the Earth would receive a lot more high-energy radiation such as gamma rays from the sun, plus cosmic rays from more energetic stars and supernova in the galaxy.
And without a magnetic field we wouldn't see any auroras (they are the result of ionized particles interacting with the magnetic field).
But if the Earth never had a magnetic field, then life would have evolved in an environment with more cosmic radiation - which could have led to increased mutations and life would be much different on Earth than it is today.

Hi. Life would have had to develop a resistance to solar emissions.

it would be chaos! there would be more hurricanes, storms all the time and we wouldn't be able to use compasses
