What are principle operation the permanent magnet?
the metal thing??
Is the magnet in a compass a permanent magnet or electronic?
A. Compasses typically use a permanent magnet.
Is a needle in a compass a permanent magnet?
Yes, it is a permanent magnet.
Is magnetite a temporary magnet?
No, it's a permanent magnet. It consists of an iron oxide, and iron is a permanent magnet.
Is the magnet in a compass a permanent magnetic or an electromagnet?
PermanentThere is no source of current in a compass, therefore the magnet is a permanent magnet.
How do permanent magnet motors work and what are the key principles behind their operation?
Permanent magnet motors work by utilizing the magnetic field generated by permanent magnets to produce motion. The key principles behind their operation include the interaction between the magnetic field of the permanent magnets and the magnetic field produced by the flow of electric current in the motor's coils. This interaction creates a force that drives the rotation of the motor's rotor, resulting in mechanical motion.
Explain how a permanent magnet windscreen wiper motor achieves 2 speeds?
Almost certainly due to the Voltage allowed to the motor by the controller (resistor). Adding a resistor will work, but is inefficient as the unused energy is wasted as heat. Two speeds are achieved by using a third brush, With the standard brushes in use. 180 derees around the commutator, current passes through all the rotor windings. The resistance sets a specific current draw and the motor runs at a standard speed. The high speed switch position feeds power in tothe motor through a third brush set at about 160 degrees from the earth brush. Current now passes through fewer rotor windings - less resistance - more current flow - higher motor speed.
What is the use of permanent magnet generator in exciter?
A permanent magnet generator in an exciter is used to provide a stable source of excitation power to the main generator. This allows the main generator to maintain voltage output and stability during operation, ensuring efficient power generation.
How can a magnet be temporarily magnetized when attached to a permanent magnet?
When a magnet is attached to a permanent magnet, it can become temporarily magnetized by aligning its magnetic domains with the strong magnetic field of the permanent magnet. This alignment causes the magnet to exhibit magnetic properties for a short period of time.
Is the magnet in a compass a permanent or electromagnet?
The magnet in a compass is a permanent magnet. It retains its magnetism without the need for an external electrical current.
Is a permanent magnet called a hard magnet or a electromagnet?
Perminant magnet
Is magnetite a magnet?
No, it's a permanent magnet. It consists of an iron oxide, and iron is a permanent magnet.
