PHYSICS 242 BLOCK 6 DRILL SET, FALL 17 Slide this drill set under Martieena 308's door any time before 7:50 AM Friday, September 29, or give it to me in Marteena 312 by 8:00 AM that day. Use one different equation from the Block 6 objectives NAME blem 1. A linear feromagnetic material has a permeability of 3.3 x 10-3 Tm/A. A magnetic field in this material has an density of 2.2 kJ/m3. Find the magnitude of the magnetic field. EQUATION USED SOLUTION ANSWER 2. Coll T has 111 turns and coll 2 has 222 turns. When no current flows in col 1 and a constant current of 2.46 flows in coil 2, the average magnetic flux from this 2.46 A current is 0.135 mWb through each turn of coil 1 and 0.246 mWb through each turn of coil 2. (Of course, the zero current in coil I gives zero magnetic flux in each turn of each coil.) Find the mutual inductance of the two coils. EQUATION USED (ONE) SOLUTION ANSWER 3. Use the data in Probicm 2 above to find the numenical value of the self-inductance of one of the two cols EQUATION USED SOLUTION ANSWER The self-inductance of coil is 4. Two coils have a mutual inductance of 6.09 mH. AL1 200 ms, the current in coll T is changing at a rate of -19,700 A/s and the current through coil 2 is a constant 2.46 A. Find the mutually-induced emf in coil 2 at that time EQUATION USED SOLUTION ANSWER 3. The displacement current is 3.3 nA through a certain area of a dielectric at 2.2 ms. The diclectric's permittivity is 44 pF/m. The electric flux through that area is C6, where C is a constant. Find C EQUATION USED SOLUTION (SHOW ALL YOUR WORK.) ANSWERExplanation / Answer
4.
induced emf is given as
E = - M (di/dt)
given that : M = 6.09 x 10-3 H
di/dt = - 19700
induced emf is given as
E = - M (di/dt) = - (6.09 x 10-3) (- 19700) = 119.97 Volts
