A practical demonstration of lenz's law and back emf in an inductive relay coil and how to solve it using a freewheeling flywheel flyback snubber clamp diode. 00:00 – recap of relays, inductors, faraday & lenz’s laws 02:30 – relay back emf explained 07:09 – the flywheel analogy of inductors 08:30 – relay circuit demonstration 12:35 – 700v back emf! 14:43 – bjt transistor storage time 17:03 – back emf diode clamp demonstrated 19:06 – an amazing demonstration!. Normally the emitter current down here matches the inductor current, but with the back emf, diode installed you'll notice that we're at 10 milliseconds per division. it takes 10 20 odd milliseconds, at least for the orange relay current here. so this is the current circulating in the back emf diode. Re: eevblog #1409 the huge trap of inductor back emf « reply #11 on: july 26, 2021, 09:20:03 pm » if you drive the relay coil with an emitter follower, no separate diode is needed (think about it), although the transistor has to pass the coil current as it ramps down to zero, with the full supply voltage across it.

a practical demonstration of lenz's law and back emf in an inductive relay coil and how to solve it using a i had made a previous video called free energy vs the laws of physics, and i had talked about some of the devices people built, voltage gain from the back emf of a coil. a description of inductive spiking, why it happens, and how a diode can save your circuits. make sure you enable annotations as a large solenoid is connected to dc power through a knife switch. when the switch is closed, the current builds up to this is a demo of back emf generated by the collapsing magnetic field. the led is connected with the opposite polarity of the the conclusion of the dc circuit fundmentals tutorial series. how a capacitor and inductor works, parallel and series see why it is extremely important to protect semiconductors from the collapsing magnetic field of inductive loads such as relay mathematical proof using faradays law and the inductance of a coil that the back emf = l (di dt). worked solution of problems from openstax university physics vol 2. inductors explained, in this tutorial we look at how inductors work, where inductors are used, why inductors are used, the different
