look up motor polling on the net.
Hysterisis losses are the losses which are taking place in the iron or steel core due to reversal of magnetisation of steel core.
hysteresis loss= K B^1.6 egs/sec where k is STEINMEITZ coefficient and B is the maximum magnetic flux density
Yes. Steel core can be used indoors. Copper core outside.
That there is steel in the middle of something.
By banging a nail it causes all the tiny domains to face different directions so you end up with a non-magnetised nail.
Because the steel strengthens the cable
First remove the dashboard to access the heater box and core! Then reversal of strip down to rebuild.
Only if the steel bolt has been magnetised, or is the core of an electromagnet.
no
yes
Because I said so Because steel remains magnetised Source: me
