In summary, the equation for calculating turns in a coil is N = mmf/reluctance, where N is the number of turns, mmf is the magnetomotive force, and reluctance is the measure of the opposition to magnetic flux. The value of reluctance for a coil is determined by the material, geometry, and number of turns in the coil, and can be calculated using the formula reluctance = length/(permeability x area). A reluctance of 12000at/wb indicates a high level of opposition to magnetic flux and can affect the efficiency and performance of the coil. The number of turns in a coil directly affects its performance, including its magnetic field strength, inductance, resistance, and efficiency. The relationship between

How many coils ??

A coil is wrapped around a magnetic core of Relectance 12000at/wb. if the mmf is 1200 AT the determined flux how many turns is the coil if 2A were flowing threw it ?

thanks, cs

Based on the given information, we can use the formula N = mmf/flux to calculate the number of turns in the coil. Plugging in the values, we get N = 1200 AT / 12000 at/wb = 0.1 turns. This means that for every 2A of current flowing through the coil, there is 0.1 turns in the coil. Therefore, to determine the total number of coils, we would need to know the current flowing through the coil. This information is missing from the given context, so we cannot accurately determine the total number of coils. However, we can use the formula N = mmf/flux to calculate the number of turns for different current values.
 

What is the equation for calculating turns in a coil with a reluctance of 12000at/wb and mmf of 1200 AT?

The equation for calculating turns in a coil is N = mmf/reluctance, where N is the number of turns, mmf is the magnetomotive force, and reluctance is the measure of the opposition to magnetic flux.

How do I determine the value of reluctance for a coil?

The value of reluctance for a coil is determined by the material, geometry, and number of turns in the coil. It can be calculated using the formula reluctance = length/(permeability x area), where length is the length of the magnetic path, permeability is the material's ability to support magnetic flux, and area is the cross-sectional area of the coil.

What is the significance of a reluctance of 12000at/wb?

A reluctance of 12000at/wb indicates a high level of opposition to magnetic flux, which means that the coil will require a large amount of magnetomotive force to generate a given magnetic flux. This can affect the efficiency and performance of the coil.

How does the number of turns in a coil affect its performance?

The number of turns in a coil has a direct impact on its performance. A higher number of turns will result in a stronger magnetic field, while a lower number of turns will produce a weaker magnetic field. Additionally, the number of turns can affect the coil's inductance, resistance, and overall efficiency.

What is the relationship between mmf and reluctance in a coil?

The relationship between mmf and reluctance in a coil is inverse. This means that as the mmf increases, the reluctance decreases, and vice versa. This relationship is described by the equation mmf = N x reluctance, where N is the number of turns in the coil.
