and a law is demonstrated with the help of an induction coil consisting of a
flexible hose carrying many turns of wire it's wrapped around a conductor when its current is turned on and induced voltage pulses observed then the current is turned off note the long time it takes for the galvanometer to equally bright now the current is turned back on of after the galvanometer has equilibrated again with the current held constant at 100 lamps the flexible hose is moved around it shown that the line integral of the magnetic field is independent of the past currents turned off again the we In the next experiment the flexible hose wraps around the current carrying conductor exactly twice when the current is turned
on the voltage pulse is twice as
large as in the 1st experiment
but In the 3rd experiment the flexible hose is held in such a way that it does not wrap around the current carrying
conductors switching the current on or off does not lead to an observable voltage pulse finally the flexible
hose wraps around to equal currents flowing in different directions so that the net current through the loop is 0 again you know in used voltage pulse is observed when the current is turned on and all
here the flexible hose is used to
measure the line integral of the magnetic field within and
outside a fairly short solenoid we have with the and the same thing the
contribution to the line integral from the outside is surprisingly small
here the line integral is measured for a permanent magnet when the flexible hose approaches and also when it subsequently removed Ch
