PHYSICS 242 BLOCK 6 DRILL SET, FALL 17 NAME Slide this drill set under Marcena 3OS's door any time before 70 AM Friday, September it to me in Mantecna 312 by 800 AM that day. Use one different caution from the Black Bobative per 1. A linear ferromagnetic material has a permeability of 33 x 10-TIAA magnetic field in this material has an density of 22Um.Find the magnitude of the magnetic field. EOLATION USED ANSWER I use as and e Coha arms and has 22 turn when no current low in some a constant current USA flows in coll 2, the a magnetic tus from this 2.46 A current is a 135 m Wb through each tum of coal and 0246 m Wb through each turm of coil 2 (Of course, the zero current in coil I gives were magnetic frust in each team of each coll find the mutual inductance of the two coils. EQUATION USED ONER) SOLUTION ANSWER TUe the data in Modem move to find the numerical value of the self-inductance of one of the two coE EQUATION USED SOLUTION ANSWER The selfinductance of collis TTwo have motion stance of a mH. A TERI ms, the current in cois changing at a rate of coil a 19,700 As and the current through coll 2 is a constant 246 A. Find the mutually-induced emi in coil 2 at the EQUATION USED SOLUTION ANSWER The displacement current EA Through a certain area of a delectance at I this. The three permitivity is 44 pion. The electric run through that area is C, where cis a constant. Find C. SOLUMON (SHOW Ai YOUR WORK.) ANSWER VmExplanation / Answer
1] fill u= 2200 J/m^3 in first box and mu = 3.3*10^-3 Tm/A
Energy density in a magnetic field is given by: u = 0.5 B^2/mu
Equation used u = 0.5 B^2/mu
2200 = 0.5*B^2/3.3e-3
B = sqrt(2200*2*3.3e-3))
= 3.81 T answer
