Magnetic force between two currents going in the same direction

WebApr 8, 2024 · When a magnetic field is changing through a coil, a current is generated in the coil which is known as induced current. The direction of this induced current is given by Lenz law. Lenz law states that, “The … WebFirst of all, the induced electromotive force is the opposite to the change of flux so E M F = − d Φ d t. The point is "the induced current tries to reduce the magnetic flux that causes it". Second of all, you are saying about induced potential but the potential itself does not imply the current - only the potential difference. hemoglobinopathies define https://fourde-mattress.com

WebMar 16, 2024 · Current which is produced by Electromagnetic Induction is called Induced Current Hence, this type of current is produced by either movement of wire or change in magnetic field Induced current is highest when direction of motion of coil is at right angle to the direction of magnetic field. Explanation WebLenz' law says that the direction of the induced current will oppose the change in flux that created it. It's not a matter of increasing and decreasing, it's a matter of direction. A decreasing flux creates an EMF that creates a current and that current will be in whatever direction it has to be to try to keep the flux from decreasing.
