What would the effects be on a earth-like planet if the magnetic field was much stronger

The hypothetical world is for all intents and purposes earth or very close to it. So what would the effects be if the magnetic field were either stronger from the start of the planet, or if the magnetic field suddenly became much stronger on a existing planet.

I already know that the planet would receive less solar radiation (possibly eliminating auroras), but other than that I don't know what else it would do, except maybe confuse animals sensitive to the earths magnetic field.

I'm looking for answers on how this might affect the evolution of life and technology, as well as the affects on both of those if the earth's magnetic field rapidly gained power.

I would like to know the affects of that a change would have from a minor one, up to a change sufficient to wipe out humanity. I'm not sure what substantial effects a powerful magnetic field could have but it seems to me that any force in a large enough amount would be able to have catastrophic effects.
