If you circulated copper wire to magnet and pass current through copper wire it then power of magnet is incrase?
The copper, technically, wouldn't increase it's power but rather extend the magnetic field of the magnet.
Does adding electric currents to something that is already magnetized increase or decrease the power of the magnet?
By 'adding electric currents', you are presumably talking about passing a d.c. current through a coil wound around a magnet?First of all, you cannot increase the flux density of a magnet beyond saturation, regardless of the current or number of turns that make up the coil. Whether on not you increase or reduce the flux density depends on the polarity of the coil compared with the polarity of the magnet; if they are opposite then, yes, you can demagnetise the magnet and, in fact, remagnetise it in the opposite direction.
How can the current on an electromagnet increase?
Yeah buddy - until something smokes. It does, and so does increasing the amp supply but you have to be careful not to melt the wire. Preferably you should increase both. -Good Luck Note; You automatically increase the amps being used by increasing the voltage applied.
What increases when current increases?
If current increases, then voltage also has to increase, assuming that resistance stay relatively the same. Power will also increase. Since power is the product of voltage and current, then the power increase would be the square of the voltage or current change.
Does transformer doubles the power?
No. Power is constant. Transformers neither increase nor decrease power, except for minor losses. They increase or decrease voltage, and they decrease or increase current, but the product of voltage and current, i.e. power, remains the same.
How current increases when the load increases in a generator?
Power is voltage times current. If you want to maintain constant voltage and yet increase power, then current must increase. Its simple math.
What happens to voltage when current is increased?
current is decreased Depends of the circuit or device: in a stepdown transformer: power in= power out, V x I = V x I , Increase voltage in (power remaining constant) you current output will increase.
How could you increase a magnet's power without using electricity?
By rubbing two magnets together.
If we increase the current then what about the power factor?
The power factor depends on the phase angle between the voltage and current on a conductor. The amplitude of the current has no effect on it.
How do you make an elctro magnet stronger?
To make a magnet more powerful you need to simply increase the flow of elctric charge going through it. For example if you connect some copper wire ina circuit and coil it around the magnet, the more coils = the more electrically charged particles = the magnetism is increased. A simple name for this is and elctro-magnet.
Why in a circuit using power I equals Watts divided by Volts when you increase voltage the current will reduce so why does this differ from Ohms law when you increase voltage the current increases?
When you increase voltage (V) then, to get the same total power (W), the current (I) must be decreased. This result comes from the Power Law: Power = voltage x current Ohms Law does not deal with power at all, it deals only with the relationship between voltage, resistance and current: Voltage = resistance x current
How as the blank applied to a circuit increases the power and the current also increase?
answer is actually voltage
