What causes a bullet to spin?
There are spiral grooves engraved on the inside of a rilfe or pistol barrel. When a bullet is fired, it is forced into those grooves, which impart a spin to the bullet. The grooves are called rifling.
How is the vacuum created in a vacuum cleaner?
Although it is called a vacuum cleaner, it does not actually create a vacuum. Inside the cleaner there is an electric motor which drives a fan blade. This fan blows air out of the vacuum cleaner and this causes air to be drawn in to the cleaner at the other end. Thus the cleaner works by creating an air flow, not a vacuum.
What causes turbines to spin in hydroelectric power?
Heat
What energy causes blades to spin?
Rotational energy
How does heat make paper spiral spin?
Heat causes air to rise by convection. As the air rises it applies pressure to the underside of the blades. This causes the paper spiral to spin.
How do you use electricfan?
The motor has a coil of wire that is an electromagnet. This causes the motor to spin, turning the fan blades.
What causes a motor to spin?
the starter
What does an electromagnet do when it is connected with wires and a motor?
It causes the motor to spin.
Do magnets make electricity?
No. Magnets create an electric feild, not electricity.However, when you spin a magnet inside a coil of wire (or you can spin the coil of wire instead), you will create an electrical current.
How does helicopter's work?
the engine inside causes the propeler to spin
Why does the coil have to spin in a generator?
A coil has to spin in a generator to produce electricity.
In an electric motor a magnetic field causes what to spin?
The rotor (which is some type of magnet).
How does a motor utilize magnetism in its operation?
If you have a coil of wire and pass a magnet trough it it will generate electricity in the coil. Similarly if you put a magnet in a coil of wire and pass electricity through the coil the magnet will move. An electric motor operates on the second principle - a rotor fitted with coils of wire is placed in side a cylinder formed from magnets and electricity is passed though the wire coils (from attachments on the rotor called brushes) and the rotor is made to spin. If however you take the same motor and mechanically spin the rotor then the reverse happens and electricity is generated - the motor becomes a dynamo.
What causes bullets to spin from firearm?
Spiral grooves cut into the inside of the barrel- known as rifling.
What is a rotating machine that transforms electric energy into mechanical energy?
There is a rotating machine that transforms electrical energy into mechanical energy. It is called a motor. These exist in many electronic gadgets, toys, and cell phones. These motors consist of a coil of wire (usully copper) and permanant magnets. When current is sent through these coils, it interacts with the magnetic field caused by the magnets, creating torque on that coil, which in turn causes it to spin. This spinning can be used as mechanical energy to power someting. An electrical motor can also be used in reverse. This is how electricity is generated. A generator is just an electrical motor in reverse. By using an engine, falling water, or steam to turn a motor, current is created inside the spinning copper coil, which can then be transmitted along a power grid.
Why does the Hoover Dam create hydro electric power?
If you spin a magnet inside a coil of wire, you will create an electric current. The stronger the magnet, or the larger the coil, or the faster the spin, the more electricity you will generate. Hydro electric power is created the same way. The water behind the dam flows through sluice gates and turns large turbines (these are like propellers) which are attached to generators that produce the electrical current. The generators are essentially magnets inside a coil of wire, or a coil of wire turning inside a magnet - either way will work.
What causes an AC 220 motor to spin counter-clockwise?
The inter changing of either the start winding or the run winding.
