i have a design that calls for a lm308 opamp, but thus opamp is discontinued, so i was wondering if there is another opamp that i can use in its place, from what i can tell the only important things are to keep the same open loop gain and it needs to work at +-9v supplys. Thanks for any help

I made the magnets out of wire and iron nails.
I made the split-ring commutator out of stripped wire.
When I hook it up to the 6V battery, it just sparks - it only looks like it wants to move.
What could be wrong? Are the magnets not strong enough?
Is the battery supplying too much/little voltage?
Thank youu!

I know that LF and HF transponders (RFID) use "inductive coupling" via the magnetic field, and UHF and microwave transponders (RFID) use "capacitive coupling" via the electric field, typically. I have heard of technology that uses a HF-UHF hybrid to overcome the difficulties that UHF technology has penetrating liquids and metals. However, I am not aware how such a technology would work, mostly because I do not know the physical reason behind the rule of thumb (LF, HF - magnetic field / UHF, microwave - electric field). My question is thus "why are magnetic fields capable of penetrating metals and liquids, when electric fields are not, and why do magnetic field applications have shorter ranges (near-field) than electric field applications (far-field)?"
