Question

1. Magnetic Field due to a Current through a Straight conductor
2. state the principal of an electric generator​

Answer 1

Answer:

1. The magnetic field produced by a current-carrying straight wire depends inversely on the distance from it and directly on the current passing through it. From this we see that the current carrying conductor produces a magnetic field around it. The direction of this magnetic field is given by Right Hand Thumb Rule.

2. Electric generators work on the principle of electromagnetic induction. A conductor coil (a copper coil tightly wound onto a metal core) is rotated rapidly between the poles of a horseshoe type magnet. ... The magnetic field will interfere with the electrons in the conductor to induce a flow of electric current inside it.
