Self Inductance Solution

Follow our step by step solution on how to calculate Self Inductance?

FIRST Step Consider the formula

L = \frac{Z \cdot Φ m}{i coil}

Next Step Substitute values of Variables

∴

L = \frac{1500 \cdot 0.05Wb}{0.012A}

Next Step Prepare to Evaluate

∴

L = \frac{1500 \cdot 0.05}{0.012}

LAST Step Evaluate

∴

L = 6250H

How to Evaluate Self Inductance?

Self Inductance evaluator uses Self Inductance = (Number of Conductors*Magnetic Flux)/Coil Current to evaluate the Self Inductance, Self Inductance is phenomenon when there is a change in the current or magnetic flux of the coil, an electromotive force is induced. This phenomenon is termed Self Inductance. Self Inductance is denoted by L symbol.

How to evaluate Self Inductance using this online evaluator? To use this online evaluator for Self Inductance, enter Number of Conductors (Z), Magnetic Flux (Φ_m) & Coil Current (i_coil) and hit the calculate button.

FAQs on Self Inductance

What is the formula to find Self Inductance?

The formula of Self Inductance is expressed as Self Inductance = (Number of Conductors*Magnetic Flux)/Coil Current. Here is an example- 6250 = (1500*0.05)/0.012.

How to calculate Self Inductance?
