Inductance Calculator

Calculate inductance in henries from magnetic flux and amperage or from resistance and time. The formula is L = Φ / I = R * t. The unit henry is calculated as 1H = 1Wb / 1A = 1Ω * 1s.
Please enter two matching values to calculate the third one, e.g. resistance and inductance to calculate time. The two values ​​to be entered are either from magnetic flux, amperage and inductance, or from resistance, time and inductance.

For example, when cooking on an induction cooker, the magnetic flux is approximately between 1 and 3 milliwebers, or say 2 mWb. A stovetop cooker can be used with an amperage of 16 amperes. In this case, the inductance is 125 microhenries.
Roughly the same result can be achieved if you take a typical induction-compatible cooking pot with a base diameter of 20 centimeters. This pot has a resistance of about 0.11 microohms. If you cook in it for 19 minutes, the inductance is 125.4 microhenries.

Electrical inductance is a physical property that describes how strongly a conductor resists a change in electric current. This conductor is usually a coil. The change in current creates a changing magnetic field. It also works the other way around: a changing magnetic field creates a change in current. This interaction between electricity and magnetism is called induction. So this is one of many forms of energy conversion.
An induction cooker works like this: a coil in the cooker creates a rapidly changing magnetic field. This induces electrical eddy currents in the base of the conductive pot on the cooker. Due to the electrical resistance there, the electrical current is converted into heat. This type of heat generation for cooking is very energy-efficient.
