transformer core material

I know what you mean, but since the current only has the length of the core to travel it's hard to grasp how that produces more than a very short pulse.

More so than an iron core?

HI PHIL!

You know, in that study you're involved in, I think you're getting the placebo.

Is that so even if we assume that it's laminated?

what else being equal?

I'm getting a bit tired of this. Learn about magnetic fields in conductors. You're in for some surprises, I'm sure.

That's fine. You don't have to answer at all. I don't know why people enter a 'basics' group though, if not for basic questions.

The problem that a core solves, is flux coupling in multiple windings. The magnetizability of a core means that it contains and directs almost all the magnetic flux. A conductor will exclude flux, which is counterproductive; even the conductivity of iron is detrimental (so lamination, or iron powder, or nonconducting ferrite is employed).

In induction motors, where the flux is intended NOT to change in the rotor (so the alternation of current rotates the rotor instead of changing its magnetization) there are aluminum parts to enhance the available torque.

When/if you don't allow the rotor to move, those rotors burn up. Almost all induction motors have thermal protection components that open if/when the motor is stalled.
