Perform general magnetic formulas and conversions.

This screen helps the operator perform the Transformer calculations of Turns Ratio, Voltage, the Current and Impedance conversions for the Turns Ratio calculations. The Core Area calculation determines the Core Area and it’s power handling. Finally the Primary Turns needed to input the magnetic field for a necessary number of turns to achieve.

Enter three knowns to calculate the unknowns. That is; enter V1, V2 and Z1 to calculate Z2. This will work for the others as well. One feature is to enter any two for one parameter and one each for the others to calculate the rest all at once. Then press “Calculate” to get the Turns, Voltage Current or Impedance in Ohms. Press “Clear” to clear the coefficients and begin over. Press the “Close” button to quit the screen and go back to main menu.

This function can figure the Inductance of a Toroidal Coil
either if two ways. One can use the inductance Factor from manufacturers data
sheets, or you can find the Inductance Index from the Area, Outer Radius and the
Permeability of the toroid. Enter the Area in

Next enter the number of turns and press “Calculate” to figure the Inductance Index and the final Inductance. As an additional feature, if just the Inductance Index is used, the user can input any of Inductance Index, Number of Turns or the Inductance. Leave any one blank and “Calculate” will figure the missing component. Press “Clear” to erase all boxes and set to default the permeability. Press “Close” to close the form and return to the main menu.

permeability. The user can also add to the lookup table by editing the INI file.
Please read notes regarding editing this file. Next the user enters the Radius,
Coil Length, Number of Turns, Current flowing thru and the over all Magnetic

This section is for computing the equivalence of force and magnetic fields. In the Single wire case it will figure force to field or field to force. In the case of Motor and Generators it will estimate the current, voltage and force needed or generated for a motor or generator.

This screen contains the function to figure the Force a
Wire in a magnetic field has or can figure from the Force the missing component
of the field makeup. Theta defaults to 90 degrees – max force. All the other
inputs can be entered and whichever is missing will be figured. That is enter
