The emf induced in the coil is 4.0x10-4 V.
What is the emf induced in the coil?
- The induced emf in a coil is determined by multiplying the coil's number of turns by the opposite of the magnetic flux's rate of change. It involves the interaction of a magnetic field and a charge.
- The induced emf is equal to (BA cos) = − d/dt. The magnetic field's strength might fluctuate over time. The region that the loop encloses is subject to vary throughout time.
- A motional emf is an emf that is caused by movement in relation to a magnetic field. The length of the object moving at speed v in relation to the magnetic field's strength B is represented by the equation emf = LvB.
Given data :
The induced emf is ε = - d/dt (BA cos θ).
- d = 4.0x10-5
- Δd = 5x10-5
- t = 0.10 s
Apply the formula ,
induced emf is ε = - d/dt (BA cos θ).
= - 4.0x10-5 / 5x10-5 x 0.10 = 4.0x10-4 V.
