Does the earth spin on its true poles or magnetic poles?
Magnetic poles
True or false the magnetic poles are not located exactly at the geographic poles?
True. The magnetic poles move constantly.
What are the three magnetic poles?
The Geographical South Pole, The Magnetic South Pole and The Southern Pole of Inaccessibility.
What is true about earths poles?
Only the magnetic poles wanderD.Earth's magnetic and geographic poles are generally not in the same place.Geographic poles are defined by Earth's rotation.
Is earth's magnetic poles and its geographic poles are in the same place?
no
How does a synchronous motor operate?
It works on the principle of "MAGNETIC LOCKING". When two unlike poles are brought near each other, there exists a tremendous force of attraction between those two poles.
Does the earth spin on its true poles or magnetic poles?
Magnetic poles
Why an input voltage exists for the motor started to move?
because of the residual magnetic flux that exists in the motor initially due to the poles
What is it called when earths magnetic poles change poles?
This is known as magnetic reversal when earth's magnetic poles change places.
Why an input voltage exists for the motor just started to move?
because of the residual magnetic flux that exists in the motor initially due to the poles
Why there is no starting torque for synchronous motor?
The 3 phase supply is provided in the stator of a synchronous motor which produces a rotating magnetic field.The stator has field poles(North and south). Now due to the rotating magnetic field the current is induced in the rotor of the motor as due to ampere's law, so the motor tends to move.Now as the stator poles induces opposite poles on the rotor, after moving the first pole pitch the rotor gets repelled by the opposite stator poles and due to the heavy inertia of the rotor it can't respond and the motor is standstill.Hence the synchronous motor is started with the help of an auxiliary motor or such called a pony motor to overcome this problem.
Do magnetic poles that are alike attract?
alike magnetic poles do not attract because according to the law of magnetism, it is stated that unlike magnetic poles attract and alike poles repel.
True or false the magnetic poles are not located exactly at the geographic poles?
True. The magnetic poles move constantly.
What is it called when Earth's magnetic poles chang places?
This is known as magnetic reversal when earth's magnetic poles change places.
Where are the magnetic forces the strongest?
magnetic poles
What are the three magnetic poles?
The Geographical South Pole, The Magnetic South Pole and The Southern Pole of Inaccessibility.
What statement is true about Earth's poles?
Only the magnetic poles wanderD.Earth's magnetic and geographic poles are generally not in the same place.Geographic poles are defined by Earth's rotation.
