5K30.40 • D+75+2

diagram for demo

The demonstration transformer shown in D+75+0 can be used to demonstrate induction melting. The secondary has been replaced with a low-resistance copper ring (ladle) of 1 turn. The ladle has an annular concavity that is filled with solidified tin. When power is applied to the primary, hundreds of amps flow in the ladle, melting the tin. The handle of the ladle is wood for thermal isolation.
