The short explanation involves you getting two permanent magnets and hold them together, if they pull together turn one around and they'll repel each other. It uses that repulsion on a much greater scale using electromagnets to hover.
Yes, some bullet trains use magnetism in a technology called magnetic levitation (maglev). Maglev trains use magnetic forces to levitate above the tracks and propel them forward, minimizing friction and allowing for faster speeds.
Homing pigeons use magnetism through tiny iron crystals in their beaks. Turtles use magnetism by sensing slight differences in magnetism throughout the ocean. It keeps them in the cycle of warm waters in a specific 8,000 mile path that they swim for years.
When current flows in a conductor there is a magnetic field formed around the conductor. This magnetic field can be used to make an electric magnet (like the ones used at junkyards), motors also use magnetism to operate, and many switches (solenoid, motor starters, and relay switches) use magnetism to open or close.
Some clocks, especially those with mechanical movements, may use magnetism in their design to regulate or control the timekeeping mechanism. For example, some clocks may use a magnetic balance wheel or electromagnetic coils to help keep time accurately. However, quartz clocks and digital clocks typically do not rely on magnetism for their operation.
People use magnetism in various ways, such as in magnetic compasses for navigation, in MRI machines for medical imaging, in electric motors and generators for converting energy, and in data storage devices like hard drives and credit cards. Magnetism is also used in everyday objects like refrigerator magnets and headphones.

No. A train that uses coal for power is a steam train, those trains referred to as 'bullet trains' usually use electricity as their motive power.
Bullet trains use electric motors powered by overhead lines or onboard batteries to propel the train forward. The trains also use magnetic levitation or steel wheels on steel rails to reduce friction and increase speed. The streamlined design of the trains minimizes air resistance, allowing them to reach high speeds efficiently.
"Bullet trains" are just electric trains.
yes the magnvy train does and i think the bullet train does to.
A bullet train is typically powered by electricity supplied through overhead lines or a third rail. The electricity powers electric motors in the train's cars, propelling it at high speeds. Some bullet trains also use a combination of electricity and diesel engines for power.
The primary thing that makes a bullet train go so fast is its low friction and aerodynamic design. Some even use magnets to allow them to float in the air for more speed.
Maglev trains use powerful magnets to create a magnetic field that repels the train from the tracks, allowing for levitation and propulsion. The system keeps the train hovering at a specific distance from the track, reducing friction and allowing for high-speed travel.
Maglev trains use the pushing power of magnetism to float over the train tracks. It's similar of pushing 2 north pole magnets away from each other.
The hummingbirds hover just out of reach.
Yes, the "old" televisions use magnetism to controll the movements of the electrons.
No
