Earth’s magnetic field
Magnet and compass
Ever wonder how a compass works to pinpoint the Arctic? Explore the interactions between a compass and a bar magnet, then add the earth and find the surprising answer! Vary the strength of the magnet, and see how things change both inside and out. Use the field meter to measure the changes in the magnetic field.
Magnetic field of a bar I
The space where the magnetic force of the magnet acts is called the magnetic field. This animation shows what the magnetic field around a magnetized bar looks like. The direction of the magnetic field is determined in the direction indicated by the N pole of the magnetic needle placed at that point.
