The discussion revolves around the effects of wire orientation in relation to magnetic fields, specifically focusing on why electromagnetic wires do not experience a motor effect when aligned parallel to a magnetic field and the implications of wire thickness on the so-called "catapult effect." The scope includes conceptual understanding and technical explanations related to electromagnetism.
Participants express varying levels of understanding and curiosity about the concepts discussed, with no consensus reached on the reasons behind the motor effect or the implications of wire thickness. Multiple competing views and questions remain unresolved.
Some terms used, such as "catapult effect" and "motor effect," may not be universally recognized, leading to potential confusion. The discussion also touches on concepts like the Lorentz Force and eddy currents without fully resolving their implications.
https://en.wikipedia.org/wiki/Catapult_effect said:In electromagnetics, the catapult effect is a phenomenon occurring when a current is passed through two wires connected by a loose wire in a magnetic field. The loose wire is then catapultedhorizontally away from the magnetic field. This occurs due to the magnetic forces acting in the wires and in the magnetic field itself.
That sounds counter-intuitive... do you have a reference which shows this? Like anorlunda, I'm unfamiliar with this subject.Josielle Abdilla said:And why does a thicker wire increases the catapult effect?
I assumed that, but I'm curious how a larger mass of conductor would incur a greater force... A larger current obviously would but a larger conductor with the same current? Suprising.anorlunda said:I suspect that the real topic is the Lorentz Force
Your first question is quite obvious. Imagine an electromagnet exerting a magnetic field towards the right. This means, that for practical purposes, it has a magnetic field going to the right. Then, we have a magnet also exerting its magnetic field to the right. Both the magnetic fields are "in sync" with each other. There is no motive for either magnetic fields to move at all. They are perfect.Josielle Abdilla said:Hii... can someone explain to me why the electromagnetic wire doesn't experience any motor effect when in parallel to the magnetic field of the permanent magnet? And why does a thicker wire increases the catapult effect?
Ty in advance :)
