Thanks for the excellent question! Magnets do impact electrical currents (for example, the flow of electrical charge through a wire). When considering the relationship between electricity and magnetism keep in mind the following key point:

• Moving electrical charges create magnetic fields and magnetic fields exert forces on moving electrical charges. The reason that I put the words "moving electrical charges" in bold is because magnetic fields only exert forces on moving electrical charges. Stationary electrical charges are not impacted by magnetic fields. Check out the following page for a nice introduction to magnetism:

A cool real-world example of how magnetism and electricity are related is a popular experiment where a compass is placed near a wire that is disconnected/connected to a battery. When no current is flowing through the wire (the wire is not connected to a battery), a compass placed near the wire will not show any deflections of the compass needle. However, when the wire is connected to a battery and current is flowing through the wire, the compass needle will deflect as the compass is moved near and around the wire. Check out the following web page for an illustration of this effect:

I hope that this helps.
