WebSo the force from current 2 on wire 1 of length L1, from here to here, is equal to current 1 times L1-- which is a vector-- cross the magnetic field created by current 2. And so we can do the same cross product here. Put our index finger in the direction of L1. That's what you do with the first element of the cross product. WebJul 3, 2024 · Answer: Magnetic forces are non contact forces; they pull or push on objects without touching them. Magnets are only attracted to a few ‘magnetic’ metals and not all matter. Magnets are attracted to and repel other magnets. Where do magnets exert magnetic forces? Every magnet produces a magnetic field that is stronger near its poles. gather financial

WebMagnetic poles. A magnet can exert a force on another nearby magnet. Magnets have two poles: a north pole. a south pole. The magnetic force is strongest near the magnet’s poles. WebMagnets can occur naturally (such as the Earth’s magnetic field), or they can be made by magnetizing ferromagnetic materials. Magnetic fields ultimately are the result of the motion of charges. A typical representation of this can be seen in the figure below. gatherfind.comWebJun 14, 2016 · 1 Answer Sorted by: 2 If you consider a "pure" electric point charge without any further characteristics such as a magnetic moment etc., then it IS NOT attracted by a permanent magnet.
