Electric field induced by current
WebThe magnetic field induced by the current that is induced, or that current that's being caused by the electromotive force and the magnitude of the force is going to be dependent on our resistance, that's going to go in the other direction, it's going to go down that way. Or it's going to induce a magnetic field that is gonna go downwards. WebJan 23, 2024 · For most red LEDs, this is around 1.7 volts. They have a positive and a negative end. This means that for the LED to turn on, the current can only go one …
