If the induced current decreases do the magnetic flux increase or decrease?
I do not know what your situation is but as a rule B would decrease when i decreases.
Situation: a straight wire is on a same plane as a circle loop. the current in the wire is traveling right, but decreasing, which makes it induced.
According to Faraday's law of electromagnetic induction, there is a proportional relationship between the induced current and the change in magnetic flux. This relationship is given by the equation:
emf = -N(dΦ/dt)
Where:
- emf is the electromotive force (voltage)
- N is the number of turns in the coil
- dΦ/dt is the rate of change of magnetic flux
From this equation, we can determine the relationship between the induced current and the magnetic flux. When the induced current decreases, it means that the emf is decreasing. And since the negative sign indicates a change in direction, this decrease in the emf implies that the rate of change of magnetic flux is increasing.
In other words, when the induced current decreases, the magnetic flux is increasing. Conversely, if the induced current increases, the magnetic flux would be decreasing.
