What is the current strength in a coil with an inductance of 0.3 H, if the current creates a resulting magnetic flow in it f = 1.5 Vb?

To find out the current in the used coil, consider the formula: Ф = Iх * L, from where we express: Iх = Ф / L.

Data: Ф – the resulting magnetic flux (Ф = 1.5 Vb); L is the inductance of the coil (L = 0.3 H).

Let’s perform the calculation: Iх = F / L = 1.5 / 0.3 = 5 A.

Answer: The current in the coil used must be 5 A.
