Why three phase induction motor has uniform torque?
The 3-phase currents in the 3 coils of an induction motor will produce a steady rotating magnetic field.
Can a dc electric field produce magnetic field?
Yes. A steady current will produce a magnetic field, B= uI/r
Do transformers use steady magnetic fields to produce an emf in the secondary?
In an AC circuit it is the fluctuation of the sine wave which causes a varying magnetic field which in turn induces a current to flow in the secondary.
Why three phase motors are self starting?
Because the three phases are 120 degrees apart which kind of gives a "rotational magnetic field" as apposed to a two phase motor (your common 220 volt motor) where the phases are 180 degrees apart and the magnetic field opposes itself until the motor is spinning.
During the first quarter cycle energy is given to an inductor. and the same amount of energy is returned by the inductor during the next quarter cycle .then how is energy stored in inductor?
Well, first of all, nobody ever claimed that the energy is stored 'in the inductor'.The energy is stored in the inductor's magnetic field.Next: When they say that energy is stored, it doesn't necessarily mean that it'sstored like in a box or a jar, and you can fill it up, put it up on the shelf, then comeback and get it in a few days.The energy stored in the magnetic field is steady as long as the current through theinductor is steady. If the current is changing, then the energy in the magnetic fieldis also changing. When the energy in the magnetic field is decreasing, then of coursethe magnetic field is returning some of its stored energy to the circuit, by way of thecurrent.
Can a changing magnetic field produce a steady electric field?
Not a steady but a moving electric field can be produced by ever changing magnetic field.
Why three phase induction motor has uniform torque?
The 3-phase currents in the 3 coils of an induction motor will produce a steady rotating magnetic field.
What is a smooth steady movement of liquid gas or electricity?
electricity
What is a steady stream of electricity?
electric current
Is a three phase induction motor self starting?
A three-phase motor has a steady rotating magnetic field generated by the stator coil, and the rotor just follows the field.
How alessandro volta invented the battery?
Constructed of alternating discs of zinc and copper, with pieces of cardboard soaked in brine between the metals, the voltaic pile produced electrical current. The metallic conducting arc was used to carry the electricity over a greater distance. Alessandro Volta's voltaic pile was the first battery that produced a reliable, steady current of electricity.
Can a dc electric field produce magnetic field?
Yes. A steady current will produce a magnetic field, B= uI/r
What is the low steady tone produced by bagpipes as an accompaniment to a melody called?
The Drone
What has the author Morton Mitchner written?
Morton Mitchner has written: 'Steady two-dimensional flow with a transverse magnetic field'
Do transformers use steady magnetic fields to produce an emf in the secondary?
In an AC circuit it is the fluctuation of the sine wave which causes a varying magnetic field which in turn induces a current to flow in the secondary.
What shape do magnetic field lines have around a wire with a steady current in it?
a circle. using your right hand, if you point your thumb in the direction of the current, your fingers will curl around the wire in the shape of the magnetic field.
What is the function of a power source in a circuit?
the function of a power source in a circuit is that it provides a steady source of static electricity
