Direction of a magnetic field
WebMagnetic Field: Region in space around a magnet where the Magnet has its Magnetic effect is called the Magnetic field of the Magnet. Let us suppose that there is a point charge q (moving with a velocity v and, located at r at a given time t) in presence of both the electric field E (r) and the magnetic field B (r). Webwhen you sleep in a way subjecting your body to cut the geomagnetic field at right angles, you become highly emotional whereas when it is Parallel, it cools your mind. Meaning, it's better to sleep with your body/bed aligned in north-south direction.

WebSep 12, 2024 · From the right-hand rule, the magnetic field d→B at P, produced by the current element Id→l is directed at an angle θ above the y -axis as shown. Since d→l is parallel along the x -axis and ˆr is in the yz -plane, the two vectors are perpendicular, so we have dB = μ0 4π Idlsinπ / 2 r2 = μ0 4π Idl y2 + R2 where we have used r2 = y2 + R2.
