Why should the flux density increase with the speed of the magnets?
It is because induction of electricity depends on rate of change of flux and it means the speed of magnet
How is Magnetic flux in a rectangular loop directly related to Magnetic force?
Magnetic flux through a loop is just a measurement of the strength of the magnetic field passing through the loop, and since magnetic field strength is directly related to magnetic force, magnetic force is directly related to the magnetic flux passing through the loop.
How are speed and distance directly related?
They are related over the time. Speed x time = distance.They are related over the time. Speed x time = distance.They are related over the time. Speed x time = distance.They are related over the time. Speed x time = distance.
In transformer core flux depends on voltage whereas leakage flux depends on current?
In a Transformer, Core flux is the difference of primary flux and Secondary flux which are opposite to each other in direction. There difference is equal to the no load flux at all loads. So, some of primary flux passes through the core and remaining becomes leakage flux (Because Secondary flux forces it to get out of the core). Same is the case with Secondary flux. Now, flux is directly proportional to Voltage and Current. When Current increases due to increased load (and voltage remains same): Then both primary and secondary flux increase. Because both of them increase, so there difference remains same. And all remaining flux is forced out. Hence leakage flux increases with current, but Core flux remains constant. When Primary Voltage is increased: Then only primary flux increases. So difference of this new increased primary flux and previous same secondary flux increases. Hence Core flux increases with voltage, But leakage flux does not. That's how In transformer core flux depends on voltage whereas leakage flux depends on current.
Is electric flux density scalar or vector?
Scalar
What is the speed of magnetic flux?
c that's the speed of light
Why should the flux density increase with the speed of the magnets?
It is because induction of electricity depends on rate of change of flux and it means the speed of magnet
What is flux density related to?
In case of electrostatics, flux density = electric field intensity and in case of magnetism, flux density = magnetic field induction
How is flux related with the strength of the magnet?
directly proportional. the greater the flux per unit area, the stronger the field.
What happens if the relative speed between the rotating flux of stator and rotor of the induction motor is zero?
if the relative speed of magnetic flux of stator and rotor becomes zero there will be no back emf and eventually the rotor gets zero speed
Why the series motor is started with some minimum load?
In series motor, At no Load Condition the flow of Armature Current is low, then the Flux is also low. Flux is inversely proportional to speed. If flux is decrease the speed is rapidly increase it spoil the rotor parts...... so SERIES MOTOR is start with LOAD.....

When pole flux of dc motor is zero what is its speed?
when the pole flux is zero there is no induced emf in the armature conductor of dc machine as a result of this there is no back emf for controlling action so speed become dangerously high or we can say it will be infinite.
What is the slip of a synchronous motor?
Synchronous motors have no slip. This is because the rotor runs at the same speed as the speed of the rotating magnetic flux of the stator.
What is the top speed of a bullet st flux RC?
35-40 mph with 2s lipo battery
How the normal speed of the dc motor can be set before varying the flux?
the normal speed of motor can be set by varing field current before using the turn
What happens if the flux of the DC machine is decreased during running?
Increasing the flux of a dc machine by increasing the field current will cause the speed to drop, because the desired amount of back emf can be created at a slower armature speed. This will allow a greater load torque to be applied so that the power output will stay approximately constant. The opposite, decreasing the flux, causes the speed to rise, but it also reduces the available torque so there is a greater chance that the motor will stall.
