Web12 sep. 2024 · The magnetic field due to current in an infinite straight wire is given by Equations [m0119_eACLLCe] (outside the wire) and [m0119_eACLLCi] (inside the wire). The magnetic field is + ϕ ^ -directed for current flowing in the + z direction, so the magnetic field lines form concentric circles perpendicular to and centered on the wire. WebThe magnetic field lines of a current-carrying loop of wire pass through the center of the loop, concentrating the field there. ... Each electromagnet has two poles, so the total force on a given magnet due to another magnet is equal to the vector sum of the forces of the other magnet's poles acting on each pole of the given magnet. cost of decorating hall stairs and landing
