When current passes through an electric bell, the armature gets magnetised and attracts the gong hence ringing the bell.
When an armature cuts through a magnetic line of force, it induces an electromotive force (EMF) due to electromagnetic induction, as described by Faraday's law. This induced EMF generates an electric current if the circuit is closed. The direction of the induced current can be determined using Lenz's law, which states that it will flow in a direction that opposes the change causing it. This principle is fundamental to the operation of electric generators and motors.
They Attract: F = iL x B
Generally we use electric switches to put on or off the light,fan,computer,music system,etc.An electric switch is a device that is used to open or close an electric circuit.when we open an electric circuit the flow of electric current inthe circuit stops and when we close an electric circuit an electric current flows through it.
If a buzzer is connected to an open circuit, it will not receive any electrical current and will not produce any sound because the circuit is incomplete. In an open circuit, there is a break in the path, so the electric current cannot flow to power the buzzer.
1. Voltmeter has high impedance and hence will restrict the current severely.a) Electric Bulb will not glowb) The Ammeter will just measure the current that Voltmeter allows and since this current is much smaller than actual current nothing will happen to ammeter.c) The Voltmeter will measure the Voltage that is being applied.d) This will allow you to measure the resistance of the Voltmeter.VR=V/I

It will get hot.
Any electrons flowing through a superconductor will show up as a regular electric current.

There is a piece of filament in every light bulb, which has so much friction that when the electric current passes through it, heat energy is produced. This heat energy is then converted to light energy.
The generator's voltage regulator will sense the fluctuation. If the voltage goes low more current will be applied to the armature to compensate. If the voltage goes high less current will be applied to the armature to compensate.
If an electric current flows through a wire, it will create a magnetic field. ... a ship or an airplane, it can damage or otherwise change the ship's magnetic compass.
An electromagnet must have a current flowing through its coil of wire in order to generate a magnetic field. When an electric current passes through the coil, it creates a magnetic field around the electromagnet.
When an electric current passes through steam, the steam gets ionized and conducts electricity. This can lead to the formation of plasma, which is a highly energized state of matter. The steam may break down into its constituent gases, hydrogen, and oxygen.
When electric current passes through water, electrolysis occurs, breaking down water into its constituent elements of hydrogen and oxygen gas. The hydrogen gas is produced at the cathode (negative electrode), while oxygen gas is produced at the anode (positive electrode).
it will run in same direction because flux and armature current both will be changed wih plarity.
