Alternating current and magnetic fields

Can you give one reason why it would not? (Assuming it has very low moment of inertia.)

The forces on the compass are identical for ac and DC for the same instantaneous current. So the only difference in the response is the inertia of the compass. For high frequencies the compass inertia will reduce the compass response dramatically.

Hey does anyone know how much will a 250MW generator cost?

sophiecentaur

An arm and a leg.

sahil2309

Ohhhh can u lend me yours??

sophiecentaur

I only wish I could help you. UK power industry is in too much of a bind, I'm afraid.

Can't even afford the scrap value....

In the images below, the magnetic field strength is graphed versus distance from the center of the conductor. It can be seen that in a nonmagnetic conductor carrying , the internal field strength rises from zero at the center to a maximum value at the surface of the conductor. The external field strength decrease with distance from the surface of the conductor.
