Magnets have a north pole and a south pole. Field line patterns show the direction and shape of a magnetic field. These diagrams are made using a plotting compass. In diagrams of a magnetic fieldthe arrows on the lines show the direction from the north to the south poles.
A magnetic field is also created when an electric current moves through a coil of wire.
Plotting compasses can be used to show the shape and direction of the magnetic field created by a coil of wire.
These are field line patterns created by electromagnets:
Magnetic field lines associated with wires carrying electric currentStraight wireMagnetic field lines associated with wires carrying electric currentFlat circular coilMagnetic field lines around a circular coilSolenoid
A solenoid is a long thin spiral of wire used to produce a magnetic field.
