WebYou need to think about the path of the magnetic field. The field is not something that flows like an electric current is electrons flowing through a conductor, but it is convenient to picture it that way. The magnetic field flows in a closed path through the center of the coil, out one end and and around the outside of the coil the the other end. WebThe field B at the centre of a circular coil of radius r is π times that due to a long straight wire at a distance r from it for equal currents. The figure shows three cases. In all cases the circular part has radius r and straight ones are infinitely long. For same current, the field B at the centre P in cases 1, 2, 3 has the ratio: Two long ...

Web19 jan. 2024 · It's true that the magnetic field can extend to great distances. It does not extend to infinity unless the current has been running for an infinite time, as anorlunda pointed out. However, the energy density stored in the field is proportional to the square of the magnetic field, and the magnetic field outside the solenoid drops off as the cube ... WebHow far does the magnetic field extend? The bullet shaped magnetic bubble formed by the terrestrial magnetic field lines is called the Earth’s magnetosphere. The magnetosphere extends into the vacuum of space, on average, from approximately 60 000 kilometres sunward, and trails out more than 300 000 kilometres away from the Sun in the magnetotail. iowa national guard asvab predictorWebClose to the magnet, that depends on the detailed shape of the magnet. Farther away (say at distances more than a few times the size of the magnet) the magnetic field will generally fall off as the cube of the distance from the magnet. If you have a small magnet, the field two feet away will only be 1/8 as strong as the field one foot away. iowa national guard armory iowa city
