The factors determining induced electromotive force (emf) in a DC machine include the strength of the magnetic field, the number of turns in the coil, the speed of rotation of the armature, and the angle of the coil relative to the magnetic field lines. The induced emf is directly proportional to the magnetic field strength, the number of turns in the coil, and the speed of rotation, while it is also affected by the angle of the coil in relation to the magnetic field. These factors collectively determine the magnitude of the induced emf in a DC machine.

If a step-up transformer has 200 turns on the primary coil and 3000 turns on the secondary coil, with a primary coil voltage of 90 volts and current of 30 amps, then the turns ratio is 200:3000, so the secondary voltage is 1350 voltage and the available current is 2 amps. (This ignores losses through the transformer.)
An ammeter consists of a coil with very low resistance. when electric current flows through the coil, the coil induces a magnetic field which turns the needle.
A step-up transformer has 100 turns on the primary coil and 500 turns on the secondary coil. If there is 120 volts and 10 amps on the primary, what will be the current in the secondary? 2 amps.600v 2A
Increasing the number of turns in the coil results in a stronger magnetic field around the coil. This increased magnetic field exerts a greater force on the magnetic needle, causing it to deflect more. The deflection of the needle is directly proportional to the strength of the magnetic field, which is why increasing the number of turns in the coil results in increased deflection of the needle.
Transformers........ you can make coil with few turns to produce required inductance.Another AnswerInductance occurs in ALL circuits. But it can be increased by winding a conductor to form a coil. It can be increased even further by using a ferromagnetic core within the coil.
The output voltage in the secondary coil would be increased. Using the transformer formula Vp/Vs = Np/Ns (where Vp = primary voltage, Vs = secondary voltage, Np = number of turns in primary coil, Ns = number of turns in secondary coil), we can calculate the output voltage to be 160 volts (40V * 100/25).
increasing the number of turns in the coil, increasing the current flowing through the coil, and inserting an iron core into the solenoid to enhance magnetic properties.
it depends on what is your low volatage. the turns of coil it's according to what is the voltage they are,When the coil / coil is equail voltage/voltage
The strength of an electromagnet is directly proportional to the number of turns in the coil. Increasing the number of turns in the coil increases the magnetic field strength produced by the electromagnet.
The secondary coil will have greater inductance compared to the primary coil because it has more turns. The inductance of a coil is directly proportional to the square of the number of turns, so increasing the number of turns increases the inductance.

Turns in a wire coil refer to the number of times the wire loops around the core of the coil. It is a measure of how tightly wound the wire is within the coil and affects the strength of the magnetic field produced by the coil. More turns generally result in a stronger magnetic field.
Increasing the number of turns in the coil of wire will most likely increase the strength of the magnetic field produced by an electromagnet. More turns of wire will result in a stronger magnetic field due to the increased current flowing through the coil.
A coil doesn't produce electrical energy, but it can store it. For a given current (amperes), the energy storage in a coil is proportional to the coil's inductance, which in turn depends on the coil's length, diameter, and number of turns. With everything else staying constant, the coil's energy storage capacity increases when the number of turns increases.
The magnitude of the magnetic field can be increased by increasing the current flowing through a wire or coil, increasing the number of turns in the coil, or using a material with higher magnetic permeability. Additionally, placing the magnetized material within a solenoid or near a strong permanent magnet can also increase the magnetic field strength.
