Name two devices which use current carrying conductor and magnetic field?
MuthuRajfb1450
One device for increasing the magnetic field surrounding a current carrying wire, is to wrap the conductor into a set of co-axial coils.
A second device is to include a ferromagnetic material in the core of such a coil.

SI unit of magnetic-induction?
Electromagnetic induction is the process of inducing electric current in a coil with the help of a magnet.Whenever a conductor is moved through a magnetic field, or the magnetic field fluctuates in strength (as with an AC electromagnet), a current will be induced in that conductor. Induction cooktops work by passing a large AC current through a conductor under the cooktop, creating a fluctuating magnetic field which induces an electric current through the cookware - heating the cookware by electrical resistance.The process by which a substance, such as iron or steel, becomes magnetized by a magnetic field. The induced magnetism is produced by the force of the field radiating from the poles of a magnet.CommentFurther to the original answer, it is a voltage that is induced into a conductor, NOT a current.
What is the noncurrent-carrying wiring devices industry?
The noncurrent-carrying wiring devices industry is made up of companies that primarily manufacture hardware used to support electrical systems
Can wiring be oversized?
There is no problem in over sizing wire by one or two sizes. Going to much larger size than needed runs you into the problem of getting the wire into terminals of over current devices. Over current device terminals are close to the correct physical size for the wire ampacity size. This happens frequently when conductors have to be over sized for voltage drop over long distance runs but still have to be protected for the load current. Never under size a conductor as this will cause heating of the wire due to the load current being higher than what the conductor is rated at.
How many overload units are required for a 3 wire 240-volt single-phase motor?
3 overloads devices required according to rule 28/304 of CEC The above answer applies to three phase motors, the NEC table 430.37 requires one overload device.
How generators use magnets?
If a conductor - such as a wire - moves through a magnetic field, a voltage is produced in the conductor. This may cause a current (if the wire is connected to an external circuit). This effect is used in generators to generate electricity.
Name two deviceswhich use currentcarrying conductor and magnetic field?
Electric motor and loud speakers are the two devices that uses current carrying conductor and magnetic field.
What is the principle of generator using motor?
Generator principle: a current moving relative to a magnetic field will have a voltage induced into it.Motor principle: a current-carrying conductor within a magnetic field will experience a force that will try to push that conductor out of the field.

What devices are based on the magnetic effect of current?
All electrical devices.
Why electronic equipments get damaged in electro magnetic field?
Answer: a changing magnetic field results in an emf, and that is basically the principal of electromagnetic induction. This means that if you pass a magnetic field across a conductor, it will induce a current in that conductor. A piece of electronics is often a semiconductor that is designed to have an exact amount of current flowing through it, and no more. If you pass a magnetic field near the semi-conductor, it may induce a current in that conductor greater that the maximum that the device was designed for, and this could result in that devices break down. The same is true of hard disk drives, accept in the case of a hard drive (magnetic storage), the device uses magnetic media to store information, and passing a magnet near it will erase the information. A common place for magnets to be found is in speaks systems.
What is SIC 3643?
The current-carrying wiring devices industry is comprised of establishments principally engaged in manufacturing current-carrying wiring devices, primarily interior electrical components used to connect equipment to a power source.
What is difference between ground and neutral?
A neutral is an active conductor in the circuit. It is grounded at the source but that's for another discussion. The ground exists to ensure the proper operation of over current devices like fuses and breakers in the event of a fault.
Doesn't a transformer work with dc from a generator?
Transformers do not work with DC. Transformers are magnetically coupled inductive devices that operate with AC (fluctuating) voltages. If you supplied DC to a transformer, it would simply look like a short circuit, and the secondary would stabilize to no voltage and no current. This is because, in order to generate a current in a conductor from a magnetic field, either the magnetic field needs to be fluctuating or the conductor needs to be moving.
What are internal storage devices?
There are three types of internal storage devices mainly optical, semi conductor and magnetic storage. Compact disk is an example of magnetic storage whereas silicon chip is an example of a semi conductor storage device.
Can heating devices be made by passing an electric current through a conductor of?
Nichrome wire works.
Why can devices be damaged if you do not provided a ground to the circuit?
Devices will not be damaged if they do not have a ground conductor in their supply cable. The ground wire is there for safety. If there is a possibility that the device could conduct a current in a fault condition and this happens, it is the ground wire current that trips the breaker and shuts the supply voltage off. There is equipment on the market that is double insulated. This means that the internal electrical current carrying parts are isolated from the frame of the device. These types of devices will have only a two wire cable supplying the voltage to it.
What machinery or devices have magnets in them and for what purpose?
The most common use of magnets and magnetism in in electric motors and generators.The basic principle of a motor is that if a wire carrying a current is in a magnet field there will be a force on that wire. That wire will move if it can.The basic principle of a generator is that if a wire is moving in a magnetic field then a current is induced in that wire.
