Enter the total magnetic flux (Weber, Wb) and the total inductance (Henry, H) into the calculator to determine the Inductor Current. 

Inductor Current Formula

The following formula is used to calculate the Inductor Current. 

Ii = MF / L
  • Where Ii is the Inductor Current (amps)
  • MF is the total magnetic flux (Weber, Wb) 
  • L is the total inductance (Henry, H) 

To calculate the inductor current, divide the total magnetic flux by the total inductance.

How to Calculate Inductor Current?

The following two example problems outline how to calculate the Inductor Current.

Example Problem #1:

  1. First, determine the total magnetic flux (Weber, Wb). In this example, the total magnetic flux (Weber, Wb) is measured to be 45.
  2. Next, determine the total inductance (Henry, H). For this problem, the total inductance (Henry, H) is calculated to be 4.
  3. Finally, calculate the Inductor Current using the formula above: 

Ii = MF / L

Inserting the values from above and solving the equation with the imputed values gives: 

Ii = 45 / 4 = 11.25 (amps)

Example Problem #2: 

Using the same process as example problem 1, we first define the variables outlined by the formula. In this case, the values are:

total magnetic flux (Weber, Wb) = 10

total inductance (Henry, H) = 9

Entering these values into the formula above gives : 

Ii = 10 / 9 = 1.111 (amps)
