| 15 | A coil of cross-sectional area A having n turns is rotated with angular velocity ω in a uniform magnetic field B. The maximum induced emf is: | 1 085 |
| 16 | ⚡ ELECTROMAGNETIC INDUCTION (EMI) — QUICK NOTES
🔹 Electromagnetic Induction
The phenomenon of inducing an emf in a conductor due to a change in magnetic flux linked with it.
🔹 Magnetic Flux
Φ = BA cosθ
where,
Φ = Magnetic Flux
B = Magnetic Field
A = Area of the Loop
θ = Angle between B and the area vector
🔹 Faraday's First Law
Whenever the magnetic flux linked with a circuit changes, an emf is induced in the circuit.
🔹 Faraday's Second Law
ε = −dΦ/dt
For a coil of N turns:
ε = −N(dΦ/dt)
🔹 Lenz's Law
The direction of the induced current is such that it opposes the change in magnetic flux that produces it.
🔹 Motional EMF
ε = Blv
where,
l = Length of the Conductor
v = Velocity of the Conductor
🔹 Induced Current
I = ε/R
🔹 Self-Inductance
ε = −L(dI/dt)
🔹 Energy Stored in an Inductor
U = ½L
🔹 Mutual Inductance
ε = −M(dI/dt)
⚡ OLYMPIAD FACTS
✓ A changing magnetic flux is necessary to induce an emf.
✓ The negative sign in Faraday's law represents Lenz's law.
✓ No emf is induced if the magnetic flux remains constant.
✓ An inductor opposes changes in current.
✓ Magnetic flux is measured in weber (Wb).
