Introducing a magnet into a coil is equivalent to increasing the number of lines of force passing through the coil.
It should be stressed that to get the full advantage of SSB transmission, receivers designed specifically for SSB reception must be used.
If a resonant circuit were completely free from losses a current once started would continue indefinitely; that is, sustained oscillations would occur.
