Question

Induced EMF in a coil during the phenomenon of electromagnetic induction is directly proportional to?

• A. change in magnetic flux
• B. rate of change in magnetic flux
• C. magnetic flux
• D. resistance of the circuit

Answer 1

Answer:

B. rate of change in magnetic flux

• The induced electromotive force (EMF) in a coil during electromagnetic induction is directly proportional to the rate of change of magnetic flux linked with the coil.

• Induced EMF in a coil during the phenomenon of electromagnetic induction is directly proportional to the rate of change in magnetic flux.

• Electromagnetic induction is the process of generating an electromotive force (EMF) in a conductor by changing the magnetic field around it.

• The magnitude of the induced EMF depends on the rate of change of magnetic flux through the coil.

• This means that the faster the magnetic field changes, the greater the induced EMF will be.
