"The core of a transformer is made in a laminated form to: "
"A. facilitate easy assembly B. reducei 2Rlosses in the coils C. increase the magneticflux D. save weight E. prevent eddy currents"
"A 6.0-mH inductor and a 3.0-Ω resistor are wired in series to a 12-V ideal battery. A switch in the ci RC uit is closed at time 0, at which time the current is zero. 2.0ms later the energy stored in the inductor is: "
"A. 0 B. 2.5×10−2J C. 1.9×10−2J D. 3.8×10−2J E. 9.6×10−3J"
Each time a corpuscle is definitely put through some sort of magnetic field these electrons inwards compass airplanes at the suitable point of view ...
Diamagnetic components use a weakened, unfavorable inclination towards magnet career fields. Diamagnetic products are generally more or less repelled...
