Magnetic field outside a solenoid
Web29 sep. 2024 · Magnetic field outside a solenoid magnetic-fields 90,582 Solution 1 You first should understand that magnetic field are the circles (of magnetic force) around the wire with current. The direction of circles (counterwise or clockwise) depends on the direction of the currend (forth or back). Web20 mei 2016 · Sho Kano said: I've read reasons along the lines of: -The magnetic field cancels out on the outside. -The field lines spread outside the solenoid so much, that the density goes to zero as the solenoid gets longer. Regarding the first statement, we know it is right but we want to know why. As for the second statement it is only a qualitative one ...

Web5 nov. 2024 · For a solenoid, there must exist a magnetic field somewhere outside the solenoid, in order for the field lines inside the solenoid to close. We can usually ignore these if the solenoid is long, as the field outside will be very weak, and very close to zero very close the solenoid (as we showed with Amp`ere’s Law above).
