5J10.10 | inductor assortment | PIRA 500 | |
5J10.10 | inductor assortment | E-12a | Sample inductors are shown. |
5J10.20 | back EMF - light bulb | PIRA 500 | |
5J10.20 | back EMF | 5J10.20 | A 20 Henry inductor energized by a 12 V battery lights a 120 V 7 1/2 W lamp when the circuit is opened. |
5J10.20 | back EMF | 31-3.6 | When current is cut off in the primary, a meter in parallel shows an induction current in the primary. |
5J10.20 | self inductance | E-252 | Open the switch of a large electromagnet with a lamp in parallel. |
5J10.20 | inductance spark | Disc 21-01 | Disconnect a 6 V battery from a 2000 turn coil to get a spark, enhance with an iron core. |
5J10.21 | back EMF | E-254 | A 4.5 V battery lights a neon bulb when the current to an inductor is disrupted. |
5J10.22 | neon back EMF | E-253 | The coils of a electromagnet are connected in parallel with a neon bulb. |
5J10.23 | neon self induction | E-12d | A neon
lamp across an inductor will glow on one side during charging and will flash
on the other when the current is interrupted. |
5J10.25 | inductance and the wheatstone bridge | E-255 | The
galvanometer in a Wheatstone bridge is connected after an inductor has reach
steady state or at the same time the current is started in the inductor. |
5J10.26 | simulating ideal self-induction | AJP 58(3),278 | A nulling circuit compensates for the steady state current in a coil. |
5J10.30 | back EMF - spark | PIRA 1000 | |
5J10.30 | back emf spark | E-12b | A one inch spark is produced when the switch of a large electromagnet is opened. |
5J10.32 | electromagnetic inertia | E-256 | A spark will jump across an almost closed loop of wire rather than go around when attached to a Leyden jar. |
