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
• Moving electrical charges create magnetic
fields and magnetic fields exert forces on moving
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.
