Chаpter 14: In the figure belоw, Cоil A hаs 5 turns оver а millimeter length and is connected to a 4.0-Ω resistor and a 12-V potential battery, while Coil B has 3 turns over a half millimeter length and is connected to a resister of 6- Ω. At time = 0 seconds, the switch is closed. Both coils have a cross-sectional area of 0.50 m2 and can be considered so close to each other that the space between them is minimal. Image alt text: Left coil with switch, resistor and emf, winding CCW as seen from right. Right coil with resistor, winding CW with point a on left, b on right of resistor. What is the self inductance of coil A? [a]( 5 points) Use the result of part (a) to answer: What is the current in coil A at time t= 0.005 s? ? Treat this as an LR circuit. [b] ( 5 points) Use the result of part (b) the answer: What is the magnetic field magnitude [c] and direction inside Coil A [d] at time t = 0.005 s due only to the current from the battery? ( 4 points) Use the information given to derive an expression and calculate the value of the mutual inductance in coil B? [e]( 4 points) What is the current direction in the resistor of circuit B at time t = 0.005 s between points a and b ? [f]( 3 points)
