No Comments on Concept of Self and Mutual Induction

Science > Physics > Electromagnetic Induction > Concept of Self and Mutual Induction In this article, we shall study the concept of self and mutual induction and also construction and working of the transformer. Concept of Self Induction: When a current flowing through a coil changes the magnetic flux linked with the coil itself changes. […]

Eddy Currents

Science > Physics > Electromagnetic Induction > Eddy Currents If a block of metal is moved in a magnetic field or kept in a changing magnetic field, the free electrons in the conductor experience force and begin to circulate. This gives rise to induced currents in closed circular paths and it is known as eddy […]

Errors and Their Types

Science > Physics > Units and Measurements > Errors and Their Types In this article, we shall study errors, their types, and terminology of errors. An error is defined as the difference between the actual or true value and the measured value. An error should not be confused with a mistake, the mistake can be […]
