A magnet is produced at the atomic level, the atoms that make up magnetic material have a "valence" electron configuration that causes the atom to have a positive and negative pole, these when are placed next to atoms of the same orientation will cause a uniform magnetic field and also the domains line up to make the magnetic field
Compass plants respond to Earth's magnetic field, but do not produce their own magnetic force.
Planet Earth
The Earth has its own magnetic field because of the movement of molten iron and nickel in its outer core. This movement generates electrical currents, which in turn create a magnetic field. The magnetic field plays a crucial role in protecting the Earth from harmful solar radiation and helps in navigation for animals that rely on Earth's magnetic field for direction.
Earth has its own magnetic field which is emitted from iron core. This protects us from harmful rays. But it does not have an electric field
Its an electro-magnet - currents flowing through the iron core.
Iron is a key element in the Earth's core and its presence helps create the planet's magnetic field. When iron-rich materials heat up and cool down, they align in the direction of the Earth's magnetic field, creating a magnetic field of their own. This process is known as the geodynamo theory and is responsible for generating the Earth's magnetic field.
The moon does not generate its own magnetic field like Earth does. The moon is considered non-magnetic because it lacks a global magnetic field that is generated by a planetary dynamo.
You don't but your compass does: it's the Earth's own magnetic field's polarity and direction.
A compass points north because of the Earth's magnetic field. The magnetic field exerts a force on the needle of a compass, aligning it with the magnetic north pole, which is close to the geographic North Pole.
Eddy currents in a magnetic drum can be produced by rotating the drum in close proximity to a magnetic field. The changing magnetic field induces currents in the metal drum, which in turn creates its own magnetic field that interacts with the original field, causing eddy currents to flow within the drum.
If there is any effect at all, it would need to be a very tiny one. The only way that the Earth's rotation might affect the Sun would be in the way the Earth's rotation generates Earth's magnetic field. Our magnetic field affects the way that coronal mass ejections, huge bubbles of ionized gas from the Sun, behave when they get close. But the Sun has a magnetic field of its own, much stronger than the Earth's field, and it is unlikely that the Earth's magnetic field would affect the Sun or the Sun's magnetic field in more than a minuscule fashion.
The Earth's magnetic field results from electric currents in the mantle and outer core around the iron solid core; every electricmagnet is prduced as a result of electricity flowing around a iron core - the same principle works in our own magnetic field.
