Planet Earth
A ring magnet interacts with the magnetic field surrounding it by creating a magnetic field of its own. This magnetic field interacts with the external magnetic field, causing attraction or repulsion depending on the alignment of the magnetic poles.
Field
Gold is not magnetic as it is a diamagnetic material, meaning it does not have a magnetic field of its own and is not attracted to magnets.
The magnetic needle is deflected due to the presence of a magnetic field that acts on the needle's own magnetic field, causing it to align in the direction of the external field. This deflection is governed by the principles of magnetism and electromagnetism.
Compass plants respond to Earth's magnetic field, but do not produce their own magnetic force.
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.
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.
Quartz is not considered magnetic because it is a diamagnetic material, meaning it does not have a magnetic field of its own and is weakly repelled by magnetic fields.
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
Yes, iron can be magnetized. When exposed to a magnetic field, the magnetic domains in iron align to create a magnetic field of its own. This causes iron to exhibit magnetic properties.
A Magnetic Force
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.
