Answear please. Not additional question or stop posting on this topic. Thank you.

My question was just will the conductor try to become circle due to current? Additional explanations are welcome but not mandatory. So Yes or No?

Thanks. Found A lot of Coil in external magnetic field, but nothing about forces from current carrying coil . Will the loop try to become circle ?

Thanks for Reply. I was expecting answer, not a question to my question though.

TL;DR Summary: Forces on Elliptical Current Carying Loop Please consider Current carrying elliptical 1-turn coil as shown in the picture. Is it true that due to forces from the current , the elliptical shape of the coil will tend to become circular ? Thank you...

So if I Increase supply frequency I INCREASE inductive reactance of the Inductor with Workpiece and if readjust the Capacitors in the LC Tank (to keep resonance state of the LC Tank) I can obtain high Q?

Also consider the Air Gap between coil and Copper Workpiece , As Shown in the picture.

Consider Parallel LC Resonance Induction heater. If we increase frequency and keep LC heater in Resonant state. There is also Air gap between coil and copper material as shown in the Picture.

Consider Parallel LC Resonance Induction heater. The material to be heated is from copper (it has relative magnetic permeability 1 and does not change with different temperatures) and is placed inside Inductor coil and there is Air gap between the coil perimeter and the material. Like this...

Thank you for Reply. It is idealised situation . No friction. No Eddy current losses. So Torque doesn't increase if we increase supply frequency, when motor uses same current.

Hi , Consider Single phase induction motor. What will be torque of induction motor, if we increase supply frequency 10 times, if the motor uses same supply current. Let's say Torque (Supply frequency 50 Hz, Supply current 10 Amperes ) = N What is Torque (Supply frequency 500 Hz, Supply...

With current Inductor with Solid Metal Core and the Eddy currents. Is it possible to have Q above 20. Inductor(with solid metal core) , Values of Capacitance of the Capacitor (Switched in Parallel or in Series) and input Frequency

Let's say Is it possible with certain values of Capacitance and Frequency to obtain Resonance with Q above 20 for the given LC Circuit?

Consider Inductor with air gap and solid metal core made from material with relative magnetic permeability 1 regardless of temperature (such as copper or aluminium). There is Air gap between coil and metal core Please Also consider Eddy currents in the solid metal core. The Inductor is...

Thanks. So the Inductive Reactance will Increase as a result of increased Frequency so
