poles(Lenze's law) . The magnetic poles of the induced current loop are also shown in the diagram . The net magnetic force on the loops is to the right. 34.3 Yes. As the loop falls the magnetic flux linked with the loop decreases hence there is an induced current in the loop in the direction shown in the diagram. The current in the wire produces a magnetic field. At point 1 this external field is OUT of the page. At point 2 the external field is INTO the page. This magnetic field passes through the loop and is the source of magnetic flux through the coil. As the loop slides by position 1, the flux through the loop is INCREASING and it is Pointing

The 12-gauge wire has a diameter of 1/12 inch while the 14-gauge wire has a diameter of 1/14 inch. Thus, 12-gauge wire has a wider cross section than 14-gauge wire. A 20-Amp circuit used for wall receptacles should be wired using 12-gauge wire and a 15-Amp circuit used for lighting and fan circuits should be wired using 14-gauge wire. Lenz's Law. The direction of the induced emf drives current around a wire loop to always oppose the change in magnetic flux that causes the emf. Lenz's law can also be considered in terms of conservation of energy. If pushing a magnet into a coil causes current, the energy in that current must have come from somewhere.
