How the magnetic field of an electromagnet defends on the current and the number of coils?
The magnetic field of an electromagnet is directly proportional to both the current passing through its coils and the number of coils. Increasing either the current or the number of coils will result in a stronger magnetic field, while decreasing them will weaken the magnetic field. This relationship is described by Ampere's law and the concept of magnetic flux.
What is the controlled variable for an electromagnetic?
One variable that needs to be controlled is the number of coils of the electromagnet as the more coils the stronger the magnetic force, so the same number of coils should be used for each test.
How do you calculate pitch using length and number of coils?
Number of coils of what? Maybe wire in an electromagnet? Please resubmit the question with more detail.
Is an electric motor and a generator very similar devices or entirely different?
They are very similar devices. They both involve a rotating shaft and coils of wire used as electromagnets. However, only certain types of simple DC motors, can be used as generators with no modiication. AC generators need careful control of the feild coils, via special circuits. Putting AC back into an AC generator will not make it work as a motor. The small DC motors found in toys, can be used directly as a small DC generator. You will find this in practice, in hand generator flashlights. The generator used for charging the battery, is no more than a model motor.
How can you change the poles of genrator?
The number of poles in a generator is determined by the engineer who designed it. The only way to change the number of poles is to completely re-manufacture the generator.
Increasing the number of loops per meter in the coils of a solenoid is one way to?
Increasing the number of loops per meter in the coils of a solenoid is one way to increase the wire's electric current.
What would increase the strength of the magnetic field?
increasing the number of coils
What effect does increasing the number of coils have on an electromagnet?
Adding more coils will make the magnetic field stronger. Magnetic field increases.
How does a Generator conductor electricity?
The generator induces a current in a wire using a magnet and a coil of wire. When the drive on a generator is rotated, a magnet inside the generator is spun around. This creates a moving magnetic field inside the generator. Located inside and around the generator is a coil of wires, which lead to a power storage device. As the magnetic field moves around, it induces a current in these wires by pushing the electrons inside the wires. The amount of electricity generated by a generator can be increased by increasing the amount of coils around the magnet, increasing the strength of the magnet, or by simply increasing the speed at which the drive is turned.
What is the different between 3phase plus N generator coil and motor coil?
Generator coils generate the voltage, motor coils use the generated voltage.
What is the effect of increasing the number of coils of wire wrapped around the core of an electromagnet?
This causes the power of the electromagnet to be increased.
In an electromagnet the magnetic force increase as increase?
Adding more coils will make the magnetic field stronger. Magnetic field increases.

What is the effect of adding more coils of wire to an electromagnetic?
Increasing the coils will increase the strength of the magnetic field.
How the strength of the electromagnets can be varied?
by increasing or decreasing the charge going through the coils or moving an iron core in and out of the coils.
How generator operates?
It works with two reactor coils for excitation of the field reactor coil , which in turn provides current to the field. The two reactor coils are connected in shunt and series with the output of the generator stator or armature ( from where load is connected).
Is you true the magnetic field around an electromagnet can be made stronger by increasing current or decreasing the number of coils around the iron core?
No, you is false. Increasing current does it, but the number of turns in the coilalso must increase if you want to increase the magnetic field that way.
