What happens when an electric current passes through a wire?
When an electric current passes through a wire, the flow of electrons creates a magnetic field around the wire. This phenomenon is known as electromagnetism. The strength of the magnetic field is directly proportional to the amount of current flowing through the wire.
What happens if the compass is placed under the wire?
Placing a compass under a current-carrying wire can cause the needle to deflect due to the magnetic field produced by the electric current. This phenomenon, known as the right-hand rule, demonstrates the relationship between electric current and magnetic fields.
What happens when you spin mercury and add electricity?
When you spin mercury and add electricity, the spinning motion can generate an electric current through electromagnetic induction. This phenomenon is known as dynamo effect. The electric current produced can be used to power electrical devices or systems.
When a current passes through a resistance what happens to the electric energy that is lost?
The electric energy that is lost in the form of heat is dissipated into the surroundings, resulting in an increase in temperature. This phenomenon is known as Joule heating.
What happens if an electric current were passed through the piezoelectric describe an application for this phenomenon?
If an electric current is passed through a piezoelectric material, it will cause the material to deform or produce mechanical vibrations. An application of this phenomenon is in piezoelectric sensors, where the electrical signal generated by the material's deformation is detected and used for various purposes such as pressure sensing, ultrasonic transducers, and touch screens.
What happens when a coil is rotated between two magnets?
When a coil is rotated between two magnets, an electric current is induced in the coil due to the changing magnetic field. This phenomenon is known as electromagnetic induction and is the basic principle behind generators and electric motors. The amount of current induced depends on the speed of rotation and the strength of the magnetic field.
What happens if a coil is rotated between two magnets?
When a coil is rotated between two magnets, an electric current is induced in the coil due to the changing magnetic field. This phenomenon is known as electromagnetic induction. The induced current produces an electromagnetic force, creating a torque that causes the coil to rotate. This is the principle behind electric generators.
What happens when electric current passes through a coil of wire?
When electric current passes through a coil of wire, a magnetic field is generated around the coil. This phenomenon is known as electromagnetic induction. The strength of the magnetic field is directly proportional to the amount of current flowing through the coil.
What happens to a electric current at a switch?
The electric charges flow without any interruption's
What happens if you turn off the electric current in the solenoid?
If you turn off the electric current in the solenoid, the solenoid quits pulling its armature.
What happens when an electric circuit is broken?
Then the current will stop flowing.
What happens when a conductor is passed through a magnetic field?
When a conductor is passed through a magnetic field, an electric current is induced in the conductor. This is known as electromagnetic induction, a phenomenon discovered by Michael Faraday in the 19th century.
