ईएमएफ के लिए क्या सूत्र है?

$\huge{\boxed{\rm{\red{Answer}}}}$

English

An emf induced by motion relative to a magnetic field is called a motional emf. This is represented by the equation emf = LvB, where L is length of the object moving at speed v relative to the strength of the magnetic field B.

Hindi

चुंबकीय क्षेत्र के सापेक्ष गति द्वारा प्रेरित एक ईएमएफ को एक प्रेरक ईएमएफ कहा जाता है। यह समीकरण ईएमएफ = एलवीबी द्वारा दर्शाया गया है, जहां एल स्ट्रेंग के सापेक्ष गति वी पर गति करने वाली वस्तु की लंबाई है

Answer 2

The formula for induced EMF is  EMF = - ΔΦ /Δt.

• Electromotive Force or EMF is said to be introduced when the rotation of the conductor or coil changes. Flow to the phone may be triggered when the telephone coil is inserted in a magnetic field that is switched off. A flexible magnetic field on the telephone coil can attract an emf in the coil that also causes a flow of energy.
• Because of the variability in the magnetic field, it can be described as the generation of possible differences in coils. In simple terms, as the flow connected to a conductor or coil increases, electromotive or EMF forces are said to be induced.
