Web6 apr. 2024 · Question 1. Views: 5,789. 1. A conducting circular loop is placed in a uniform magnetic field B =0.020 T with its plane perpendicular to the field. Somehow, the radius of the loop starts shrinking at a constant rate of 1.0 mm/s. Find the induced emf in the loop at an instant when the radius is 2 cm . 2. Web12 sep. 2024 · Consequently, an emf is induced in each circuit by the changing current in the other. This type of emf is therefore called a mutually induced emf, and the phenomenon that occurs is known as mutual inductance (M). As an example, let’s consider two tightly wound coils (Figure 14.2. 1 ).
