What kind of energy does a compass use?
A compass does not use energy to function, as it relies on Earth's magnetic field for its operation. The needle in a compass aligns itself with the Earth's magnetic field, pointing towards the magnetic North Pole.
Do magnetic field lines close together indicate a weaker magnetic field?
No, magnetic field lines close together indicate a stronger magnetic field, while magnetic field lines farther apart indicate a weaker magnetic field. The density of field lines represents the strength of the magnetic field in that region.
How can you see the invisible magnetic field?
You can see the invisible magnetic field by using iron filings. When sprinkled around a magnet, the iron filings align themselves to the magnetic field lines, making the lines visible. This technique helps visualize the magnetic field's direction and strength.
Does Ceres have a magnetic field?
No, Ceres does not have a global magnetic field. It is thought to have a partially differentiated interior, which may be why it lacks a magnetic field.
Where do you use magnetic field?
In a magnetic compass, electric motors, security system sensors and a whole lot more.
