Difference between a magnetic field and an electric field

Nicholas.D

1. The problem statement, all variables and given/known data
Describe the difference between a magnetic field and an electric one.

2. Relevant equations
N/A

3. The attempt at a solution
I thought the two were the same or at least linked somehow. I don't understand why a proton will not achieve an increase of decrease in Ek when going through a magnetic field, but will under an electric field.
