Why a coil of wire with a direct current passing through it will magnetise a piece of iron?
The coil would act as if a bar magnet inserted along its axis. So any iron material inserted gets magnetised.
A coil that is magnetized only when an electric current flows through it?
Yes true. Even without the iron core as current passes through the coil then the coil would act as a magnetic shell. If the wire is wound in a helical form, then the device is known as solenoid. So with the current in the solenoid it would act as if a bar magnet. If iron core is introduced then the magnetic lines would be concentrated and hence an intense magnet could be produced. The pole of this system will be determined by using 'end rule'.
How do I know the direction of the torque acting on coil whether its vertical or horizontal?
To know the direction of the torque acting on the coil, whether the coil is vertical or horizontal, you will compare the direction of the magnetic force or its rotation to the direction of the coil. If the coil is vertical and the magnetic force is in the direction of the coil rotation, then the direction of the torque will be the same.
Is a coil a conductor?
heater coil is good conductor of electricity
What is A sentence for the word coil?
One way you can write it is : She had to coil it around to activate it.Or you could say: I had to coil it for a project.
What does a electromagnet have that a bar magnet does not have?
The bar magnet and the electromagnet act identical. The difference being a electromagnet is a coil of wire that has a power source connect to both ends, this energizes the coil with an electromagnetic field.
Why a coil of wire with a direct current passing through it will magnetise a piece of iron?
The coil would act as if a bar magnet inserted along its axis. So any iron material inserted gets magnetised.
Is diode an active device?
A passive device is a diode resistor coil and so forth it perform no enhancement to the circuit or act on it.
Where is the coil pack on a 1992 Pontiac Grand Am?
The coil pack for a 1992 grand am is under the cover that has quad 4 written on it, be careful not to let anything drop into the valley when the cover is pulled off. The coil pack is white and there are 4 black rubber boots that act as the spark plug wires.
Do you add electrical supply voltage and induced voltage of a coil to get total voltage on the coil?
The induced voltage acts to oppose any change in current that is causing it. So, if the current is increasing, then the induced voltage will act in the opposite direction to the supply voltage; if the current is decreasing, then the induced voltage will act in the same direction as the supply voltage.
What force makes the coilgun work?
the force of objects being attracted by magnets. the coils or solenoids act as magnets and the projectile (which must be able to attract to magnets, often iron or steel is used) is attracted to the coils. but when the projectile reaches the coil the coil must be turned off so the projectile keeps going instead of stopping at the coil.
Is a relay considered a load?
The relay's coil(s) would be a load, but the main function of a relay is to act as a switch to control power to a larger load.
Where is the coil wire located on a 1997 Chrysler Sebring LXI 2.5L?
The coil is inside the distributor. There is no coil wire.The coil is inside the distributor. There is no coil wire.
Is it lucina coil or lukina coil?
Lacuna coil
What is the difference between current coil and voltage coil?
These terms apply to the coils inside a wattmeter. 'Pressure coil' is an archaic term for 'voltage coil', which is connected in parallel with the supply, while the 'current coil' is connected in series with the load.
Can a bad ignition coil just shut your car off?
The engine would shut down, but the rest of the vehicle would act as if the ignitoin was in the acc on position.
How do you spell koil?
The word sought may be coil (a wound string, cord, wire, or act by a snake).The proper noun Koil is an Indonesian rock band.
