Homework Answers
In AC current or voltage oscillate due to which direction of current or voltage change after each half cycle so current flow in forward direction for half of the time and in reverse direction for next half of the time. Work done by this current is mostly zero in capacitor and inductor or do no work and energy losses are minimum too. So option is most appropriate option as net magntic field by AC is zero.
And it oscillates and it is not a constant horizontal flow.

In our daily life, we often use the electric charger to charge our cell phone or laptop. There will be currents going through the charger when we use them, and the magnetic field should be created by the current. But if we test the magnetic field around the charger, we will find almost zero magnetic field. What is its most accurate explanation? Part A The given information is not sufficient to get the right explanation. The currents are too big,...
