WebFeb 6, 2024 · Introduction: To understand the questions we need to understand the meaning of induced emf for a loop at rest. For such loop induced emf is defined as the work done by net NON-conservative electric field on a charge divided by the charge. Hence it is a scalar quantity. Mathematically: ϵ = ∮ C E → ⋅ d l →. WebBack emf is the generator output of a motor, and so it is proportional to the motor’s angular velocity . It is zero when the motor is first turned on, meaning that the coil receives the full driving voltage and the motor …

"Inside a source of emf (such as a battery) that is open-circuited, a charge separation occurs between the negative terminal N and the positive terminal P. This leads to an electrostatic field that points from P to N, whereas the emf of the source must be able to drive current from N to P when connected to a circuit. This led Max Abraham to introduce the concept of a nonelectrostatic field that exists only inside the source of emf. In the open-circuit case, , while when the source is connect… " - Emf physik
