Circles of Magnetism I by Exploratorium

In this experiment, you’ll learn that compass needles are little magnets that are free to rotate. Compasses allow us to observe the direction of a magnetic field. Normally, they respond to the earth’s magnetic field, orienting themselves parallel to magnetic field lines. If we create a magnetic field that is stronger than the field of the earth – for example, by using electric currents – a compass needle will orient itself parallel to the new field.
