How megnetic field produce a current
WebWith a typical bar magnet, for example, the field goes from the north pole to the south pole outside the magnet, and back from south to north inside the magnet. Electric fields … Web17 apr. 2024 · How do mri scans work MRI scanners produce a strong magnetic field that forces protons in the human body to align with it. A radiofrequency current is then pulsed through the patient which stimulates these protons, causing them to spin out of equilibrium and strain against the pull of the magnetic field.

WebThe magnetic field produced by the current moves in the same direction at the point they intersect. Since like poles always repel, the magnetic field produced due to the current flowing in the parallel wires in the opposite direction repels. Solved Problems on the magnetic field between two parallel wires WebThe magnetic field created by current following any path is the sum (or integral) of the fields due to segments along the path (magnitude and direction as for a straight wire), …
