How does water affect the magnet field?
No it doesnt affect it. In fact there are some compasses that utilize water as a surface. If the water caused a problem with the magnetic field of the earth, it would be useless for creating a compass; it would never be correct.
How do you separate magnetic and nonmagnetic particles?
A non-magnetized piece of iron would capture the magnetic particles.
Would the size of a magnet affect the sound quality through a speaker?
Yes a greater magnetic field would alter the sound produced and (if other factors remained the same) the effect required by the amplifier to reach a given sound pressure level.
What if earth's magnetic field did not occasionally reverse polarity?
We expect Earth would still have a magnetic field during a reversal, but it would be weaker than normal with multiple magnetic poles. Radio communication would deteriorate, navigation by magnetic compass would be difficult and migratory animals might have problems. Many migratory animals use the geomagnetic field to orient themselves. However, even if Earth's magnetic field began a reversal, it would still take several thousand years to complete a reversal.
Are most substances magnetic?
Technically all substances are magnetic in some way: it's either ferromagnetic (what most people would consider "magnetic"), paramagnetic (weakly attracted to a magnetic field), or diamagnetic (weakly repelled by a magnetic field). Not many substances are "magnetic" in the usual lay meaning of the word, though.
How a simple transformer can be made?
The absolute simplest transformer would be two pieces of wire laid next to each other. Changing current in one wire would induce a magnetic field that in turn induced a current in the other wire. This would not be efficient though. Coiling the wires concentrically would increase their interaction and efficiency, but for a functional, simple transformer, wrapping the wires around a soft ferromagnetic materiel with a high magnetic permeability and high field saturation makes for a much more efficient transformer.
Why would direct current be unsiutable for transformers?
A transformer is a device that transfers electrical energy from one circuit to another through inductively coupled conductors-the transformer's coils. A varying current in the first or primary winding creates a varying magnetic flux in the transformer's core, and thus a varying magnetic field through the secondary winding. This varying magnetic field induces a varying electromotive force (EMF) or "voltage" in the secondary winding. This effect is called mutual induction.Transformers depend on the changing of magnetic fields within the transformer. Direct current would cause a magnetic field to form in the primary coil, but its the change that induces the current in the secondary field. the change only occurs if an alternating current is applied.
Does a condenser affect the performance of the car?
The AC condenser would effect the performance of the AC system in the car.
Does water affect the magnetic field?
No it doesnt affect it. In fact there are some compasses that utilize water as a surface. If the water caused a problem with the magnetic field of the earth, it would be useless for creating a compass; it would never be correct.
Why could the weather affect a performance in the globe theatre?
It didnt have a roof if there was bad weather if would spoil the performance
Would a new transmission have anything to do with evap or egr codes on 97 1500 5.7 2wd w shift kit?
No it would not. Transmission performance does not affect the engine. But engine performance does affect the transmission.
What does transformer coupled mean?
It means a signal has no direct (galvanic) connection to the next circuit, rather, the signal is sent (coupled) only through the magnetic field in the transformer. This is used where unwanted DC current would flow, or where a ground loop would result if a direct connection was used.
Do magnetic underlays affect peacemakers?
Magnetic underlays affect on pacemakers are theorized currently. There are theories that they do have an effect on blood supply if used while there are some theories that do not support this concept. I would suggest consulting with your physician.
Does the size of a parachute affect its performance?
Yes! I would not want to jump with a miniaturized parachute...
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.
In D.C supply the transformer is not connected why?
In a DC power supply a transformer is connected. The only time there would be no transformer used would be if the DC voltage wanted was 120 VDC. The transformer in the power supply is connected to 120 VAC on the primary side and the secondary side of the transformer is connected to either a half wave or a full wave diode bridge. The voltage out of the diode bridge will be the same output voltage potential as the transformer's secondary voltage but it will be a DC (Direct Current) potential.Reading the question in another way, transformers are not connected in a DC circuit. The reason being is that the transformer operates on a collapsing magnetic field. This field induces a voltage into the secondary side of the transformer. Since the DC circuit does not operate on the principle of a collapsing field except when the circuit is opened, the transformer would not operate as a transformer should..
What happen if wood is used for making transformer core instead of iron?
It would not function. In general, the core must be made of a material with certain magnetic properties. Wood has none.
