- Coil A is a large 1000 turn circular coil of radius 68.0 cm. Circular coil B has 200 turns, a radius of 3.0 cm and is located L = 56.0 cm from coil A along the same axis. The planes of the two coils are parallel. Find approximately the mutual inductance of this pair of coils. *Note* As coil A is much larger than coil B, the B field due to A in the region of B is fairly constant. Use this approximation and proceed.Shown in the following figure is a long, straight wire and a single-turn rectangular loop, both of which lie in the plane of the page. The wire is parallel to the long sides of the loop and is 0.5 m away from the closer side. At an instant when the voltage induced in the loop is 2.5 V, what is the time rate of change of the current in the wire? 0.50 m] 3.0 m 0.50 m a. What is the expression for magnetic field B due to the current I in the long, straight wire, at distance r away from the wire? B = . Give your answer in terms of given variables (I, r) and physical and numerical constants (o, T, ke, and/or c). Spell out Greek letters and use underscore ("_") for subscripts. b. Because the magnetic field is not uniform, you will have to use integration to calculate the magnetic flux, = = [₁ BdA. Find the magnetic flux through the loop as a function of I ( will be proportional to I, as shown below; find the coefficient, in base SI units). Hint for (b) Φ I. Give your answer in terms of given….
- In your own words, explain why the presence of a ferromagnetic core increases the inductance of a coil. Calculate the inductance of a coil wound on a ferromagnetic cylinder of 2 mm diameter and 10 mm length. There are 200 turns on the coil and the relative permeability of the core is 600. How does a real inductor differ from an ideal component?Do it correctlyIn (Figure 1), RRR = 16.0 ΩΩ and the battery emf is 6.30 VV. With switch S2S2 open, switch S1S1 is closed. After several minutes, S1S1 is opened and S2S2 is closed. a) At 2.40 msms after S1S1 is opened, the current has decayed to 0.210 AA. Calculate the inductance of the coil. b) How long after S1S1 is opened will the current reach 1.00%% of its original value?
