WebOct 21, 2024 · Move the wire or move the magnet so the magnetic field inside the wire fluctuates and electricity will flow through the wire. Keep moving the wire or magnet and you'll make electricity continually. You can … Webin the primary coil results in surges of current in the secondary coil. The effect is stronger if both coils are winded around an iron ring. The primary coil creates a magnetic field that goes throgh the secondary coil, too. If the magnetic field changes with time, an electromotive force (EMF) develops in both coils.
