Oh, I think I see the "wires" now. It's pretty confusing, so let me try to introduce a coordinate system. Let ##W## be the width of the flat magnet and ##T## be the vertical thickness. The ##(x,y,z)## axes point right, back and up.StoyanNikolov said:
Yes, the magnetic field of the wires will exert a force on the magnet. The same thing happens if you just have a wire instead of a bar magnet as the field from each part of the wire exerts a force on each other part.StoyanNikolov said:
Why wouldn't it keep moving? I'm having a hard time seeing what the restoring force is that establishes an equilibrium position.berkeman said:
Conservation of Momentum probably. I think there would be a counter-force from the bunching of the current once that offset forms, but I'd have to think more about it...DaveE said:
On a large scale, I don't see how it's different that a battery powered toy car, but with a linear motor instead of a rotary motor. Momentum isn't conserved when you are discharging energy in a battery to apply force.berkeman said:
OK, not so obvious to me now. Let's say the battery, magnet, and wires area all glued to a platform so none of that stuff moves, and it's floating in space. There is a Lorentz force at the magnet, but that B-field wraps around and goes through the battery and the rest. It's stronger at the magnet, so if you integrate around the current loop I think you get a net force.berkeman said:
Yea, I get it. I'm focused too much on the electrons here. There are also protons present...berkeman said:Now don't you be posting about Reactionless Drives...
Yes, conducting current through a bar magnet can cause it to move due to the interaction of the magnetic field generated by the current with external magnetic fields. This phenomenon is explained by the principles of electromagnetism, specifically the Lorentz force.
The Lorentz force is the force experienced by a charged particle moving through a magnetic field. When current flows through a bar magnet, the moving charges within the magnet interact with external magnetic fields, resulting in a force that can cause movement. This force is perpendicular to both the direction of the current and the magnetic field.
Yes, the orientation of the bar magnet significantly affects its movement. The direction and magnitude of the Lorentz force depend on the alignment of the magnet's magnetic field with the external magnetic field and the direction of the current. Different orientations can result in different types of motion, such as rotation or linear displacement.
Yes, this principle is utilized in various practical applications, such as in electric motors and generators. In these devices, the interaction between current-carrying conductors and magnetic fields is harnessed to produce mechanical motion or generate electricity.
Yes, there are safety concerns to consider. Conducting current through a bar magnet can generate significant heat, potentially leading to overheating or damage. Additionally, strong magnetic fields and high currents can pose risks of electric shock or magnetic interference with electronic devices. Proper precautions and safety measures should be taken to mitigate these risks.
