What are the ways to increase the amount of induced current in electromagnetic induction?
1 Answer
The amount of induced current can be increased by :
- Increasing the number f turns in coil.
- increasing the number of magnets used
- increasing the rate of change in magnetic flux.
A current can be induced in a conducting loop if it is exposed to a changing magnetic field. ... In other words, if the applied magnetic field is increasing, the current in the wire will flow in such a way that the magnetic field that it generates around the wire will decrease the applied magnetic field.The current induced in a conducting loop that is exposed to a changing magnetic field is known as induced current.
Right hand rule gives the current direction shown, and the polarity of the rod will drive such a current. To find the magnitude of EMF induced along the moving rod, we use Faraday's law of induction without the sign: EMF=NΔΦΔt EMF = N Δ Φ Δ t . In this equation, N=1 and the flux Φ=BAcosθ.
Both are current flow but generally speaking you have induced current in a conductor if it is in close proximity to another conductor. ... Current flow in a conductor produces a magnetic field around the conductor. Any other conductor moving through that magnetic field will have a current induced in it.
An emf is induced in the coil when a bar magnet is pushed in and out of it. Emfs of opposite signs are produced by motion in opposite directions, and the emfs are also reversed by reversing poles. The same results are produced if the coil is moved rather than the magnet—it is the relative motion that is important.
