Magnetic poles
The two ends of an electromagnet are called the north pole and the south pole. These ends are where the magnetic field lines originate and terminate, respectively.
The mental center of an electromagnet is called the magnetic pole. It is the point on the electromagnet where the magnetic field is concentrated and strongest.
Reversing the current flow in an electromagnet changes the direction of the magnetic field it produces. This can be useful for changing the polarity of the electromagnet or controlling the direction of a mechanical system it is used in.
The rotating electromagnet in an alternator is called the rotor.
To make an electromagnet toy, you will need a battery, insulated copper wire, a small metal rod or nail, and a switch. Wind the copper wire around the metal rod tightly, leaving ends free. Connect the wire ends to the battery terminals with the switch in between and when you turn on the switch, the current will flow through the wire creating a magnetic field, turning it into an electromagnet.
