The ohm’s law can be derived from the equation J= σE. Consider a segment of wire of length l and cross sectional area A as shown in figure When a potential difference Vis applied across the wire, a net electric field is created in the wire which constitutes the current in the wire. For simplicity, we

When a conductor moves in a magnetic field, the direction of motion of the conductor, the field and the induced current are given by Fleming’s right hand rule and is as follows: The thumb, index finger and middle finger of right hand are stretched out in mutually perpendicular directions. If the index finger points the
