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.
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.
The factors that affect the voltage produced by a dynamo include the speed of rotation, the strength of the magnetic field, the number of turns in the coil, and the size of the wire used in the coil. All these factors contribute to the amount of electromagnetic induction that occurs and thus influence the generated voltage.
Electric charges must be in motion to produce a magnetic field. When electric charges move, they generate a magnetic field around them. The strength of the magnetic field depends on the speed and direction of the moving charges.
A charge moving perpendicular to a magnetic field experiences a force that is perpendicular to both the charge's velocity and the magnetic field direction. This force causes the charge to move in a circular path around the field lines, with the radius of the circle determined by the charge's speed and the strength of the magnetic field. This phenomenon is known as magnetic deflection.
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.

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
A slower rotation of the Earth would likely result in a weaker magnetic field due to the relationship between the planet's rotation and the geodynamo process that generates the magnetic field. A slower rotation may impact the convection of molten iron in the Earth's outer core, which is a key factor in the generation of the 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.
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.
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
Alpha particles with the same energy as beta particles have much less speed, magnetic field or no.
Slip power is the electrical power that is converted into mechanical power due to the slip between the stator magnetic field and rotor in an induction motor. It is the power required to maintain the rotor's rotation at a speed slightly lower than the synchronous speed of the stator field.
The factors that affect the voltage produced by a dynamo include the speed of rotation, the strength of the magnetic field, the number of turns in the coil, and the size of the wire used in the coil. All these factors contribute to the amount of electromagnetic induction that occurs and thus influence the generated voltage.
Slip is referred to as the difference between the speed of the rotor and the speed of the rotating magnetic field in the stator of the induction motor. Speed of the rotor=n(1-s) Speed of the rotating magnetic field= f/p
