Final answer:
Electrical fields differ from magnetic fields as they can act on both charged and uncharged objects, whereas magnetic fields only affect moving charges. Magnetic fields induce current in conductors when changing and are visualized by continuous field lines without a start or end, unlike electrical fields which originate on positive charges and terminate on negative charges.
Step-by-step explanation:
What do electrical fields do that magnetic fields don't?
- Generate electric currents in conductors.
- Generate magnetic fields in conductors.
- Act on charged and uncharged objects.
- Exhibit attractive and repulsive forces on charged particles.
Electrical fields do not generate electric currents in conductors or magnetic fields; these are properties of magnetic fields. Magnetic fields are generated by moving charges or by changing electric fields and can induce an electric current in a conductor when the magnetic field changes. Moreover, magnetic fields act on moving charges, influencing their direction according to the right hand rule, but do not act on stationary uncharged objects. Electrical fields exert forces on charged particles, with the direction of the force depending on the sign of the charge. Electrical fields can also exhibit both attractive and repulsive forces on these particles, emanating from positive charges and terminating on negative ones, whereas the behavior of magnetic field lines is different - they are continuous loops with no starts or ends due to the absence of magnetic monopoles. Therefore, the correct answer is that electrical fields act on both charged and uncharged objects while magnetic fields do not.
