C) An alternating current Will flow in the wire. As current begins to flow through one loop of an electric coil, the expansion of the magnetic field in that loop will create a Counter ElectroMotive Force (CEMF) in the adjacent loops of the coil. B) A uniform current will start to flow in the wire. Once current begins to flow, electrons are now moving through the circuit. Although current and voltage are interconnected by the resistance, current cannot exist without a voltage. The action of CEMF on a coiled wire is called Inductive Reactance This reactance will Impede or slow down any increase in current flow through any coil. When the thermostat closes, current begins to flow through this coil, which becomes magnetized, and closes the contact on the start winding. Specifically are electrons "used up" or do they simply lose energy (dissipated as heat in circuit) which leads to a lower voltage potential? If these terminals are connected with a wire, a current begins to flow due to the voltage difference between the terminals. A magnetic field that is controlled by current flow through a coil connected in series with the Run winding. A velocity perpendicular to a magnetic field B transforms in an electric field E that is both orthogonal to the velocity and the B field. suppose a ring is placed in changing flux . magnetism, what will happen if we Illuminate a metal wire with light from a laser pointer? According to the Ohm’s Law, the current in a conductor proportionally changes with the voltage. As for single charges, the current must be moving in a direction other than the direction of the field. This can help you determine what the direction of the magnetic field will be. When this happens, the "light bulb" person stops glowing by lowering or "melting down" to the floor.

Current flows from the negative end of a battery, through the wire, to the positive end of the battery. So, the current changes it's direction and it continues to flow this way until again the pink wire comes on the left side, because now again, the pink wire starts going up, the blue wire starts going down, and as a result the current in the pink wire will be inwards, the current in the blue wire will now be outwards, the current will again reverse. A short circuit is any electrical flow that strays outside its intended circuit with little or no resistance to that flow. An electric current flowing in a wire creates a magnetic field around the wire, due to Ampere's law (see drawing below). While no current flows in the left-hand coil there will be no effect on the right-hand coil and the detector remains at zero (figure 6.5a). Does this mean that the voltage actually begins to decrease as a direct result of current flow? To concentrate the magnetic field, in an electromagnet the wire is wound into a coil with many turns of wire lying side by side. This means when you change the direction of the current, you also change the direction of the magnetic field. When the switch is closed the current begins to flow through the left-hand coil, however it will not reach a steady value immediately but increases gradually because of Lenz’s law. When the student "switch" changes his/her paper to "switch on," the flow begins again and the electrons start moving like "hot potato" around the circle. the flux density represents the B-field. When the switch goes off, the flow of electrons stops, so the current stops. The magnetic field of all the turns of wire passes through the center of the coil, creating a strong magnetic field there.
