What is the factors on which the induced EMF in a coil rotating in a uniform magnetic field depends?
The induced EMF in a coil rotating in a uniform magnetic field depends on the strength of the magnetic field, the number of turns in the coil, the area of the coil, the speed of rotation, and the angle between the magnetic field and the plane of the coil.
What can be done to increase the speed of rotation of the coil?
To increase the speed of rotation of the coil, you can increase the voltage applied to the coil or reduce the resistance in the circuit. Additionally, using a stronger magnetic field or reducing the friction in the system can also help increase the speed of rotation.
How does the magnetic field affect the speed of a particle?
The magnetic field can change the direction of a charged particle's movement, but it does not directly affect its speed.
What is the radius of the ion's path in the magnetic field?
The radius of the ion's path in the magnetic field is determined by the ion's charge, speed, and the strength of the magnetic field.
What is the relationship between electrical frequency and magnetic field speed for an ac machine?
In an AC machine, the electrical frequency of the input power supply determines the rotational speed of the magnetic field, which interacts with the conductors in the machine to produce electrical power. The relationship between electrical frequency and magnetic field speed is directly proportional – an increase in electrical frequency results in a corresponding increase in the speed of the rotating magnetic field.
Does the moon have an active magnetic field?
To have an active magnetic field you must have a reasonably fast rotation speed, and a molten metal core. The earths moon has neither of these, so the answer is No, the moon doesn't have a magnetic field of any kind.

What is the function of field winding in DC generator?
The motor needs the current and magnetic flux to create motion The magnetic field is created by field winding where as armature carries the current resulting into the rotation of armature
If the earth rotated more slowly would you expect it to have as strong a magnetic field?
No it would probably weaken. The Earth's magnetic field is due to a combination of two factors: Earth's relatively high iron content and Earth's relatively high rotation speed. If you reduced either factor you should expect the magnetic field's strength to be reduced.

What is the factors determining induced emf in dc machine?
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.
What is the relationship between electrical frequency and magnetic field speed for an ac machine?
In an AC machine, the electrical frequency of the input power supply determines the rotational speed of the magnetic field, which interacts with the conductors in the machine to produce electrical power. The relationship between electrical frequency and magnetic field speed is directly proportional – an increase in electrical frequency results in a corresponding increase in the speed of the rotating magnetic field.
2 The air gap between stator and armature of an electric motor is kept as small as possible?
a. To get a stronger magnetic field b. to improve the air circulation c. To reach the higher speed of rotation d. To make the rotation easier
Does an alpha particle and beta particle has the same speed in a magnetic field?
Alpha particles with the same energy as beta particles have much less speed, magnetic field or no.
