Ferromagnetic Windings in Electric Motors: Can They Operate?

AI Thread Summary
Ferromagnetic wire windings can technically operate in electric motors, but they are not advisable due to their high resistance compared to copper. While eddy currents are lower in ferromagnetic materials, the overall performance of the motor could be compromised. The magnetic properties of ferromagnetic wires may interfere with the motor's magnetic design, affecting efficiency. Using such materials could lead to suboptimal performance and increased heat generation. Therefore, copper remains the preferred choice for motor windings to ensure optimal functionality.

Can the wire windings in an electric motor be ferromagnetic and still operate? Why?
 
Physics news on Phys.org
The motor could still operate with (formvar-enamel coated) ferromagnetic wires, but it would be a poor choice in part because it is very resistive relative to the same size copper wire. Eddy currents in the wire are lower than in copper, due to the higher resistance. The magnetic properties of a ferromagnetic wire might alter the magnetic design of the motor poles or armature, and degrade the motor performance.
 

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
