What is light classiified as when electrical and magnetic fields vibrate in a light wave?
Light is classified as an electromagnetic wave when electrical and magnetic fields vibrate in a light wave. This type of wave does not require a medium to propagate and can travel through empty space.
Why is a magnet used in a speaker?
A magnet is used in a speaker to create a magnetic field that interacts with an electrical current, causing the speaker cone to vibrate and produce sound waves.
What causes a vibrating magnetic field?
A vibrating magnetic field can be caused by alternating current flowing through a conductor, which generates a changing magnetic field around the conductor. This changing magnetic field can induce a current in nearby conductors, causing them to vibrate as well. Other sources of vibrating magnetic fields can include electromagnetic radiation and electrical motors.
How does the wire vibrate if the magnetic field is made vertical in sonometer experiment?
If the magnetic field is made vertical in a sonometer experiment, the wire will vibrate in a direction perpendicular to the magnetic field. This is because the Lorentz force, which causes the wire to move, is perpendicular to both the current flowing in the wire and the magnetic field. This results in the wire moving up and down, or side to side, depending on the setup.
Why do power lines hum?
Power lines hum due to the vibration of the electrical current running through them, which creates a magnetic field that causes the wires to vibrate and produce a low-frequency sound.

Does heat weaken in a magnetic field?
Yes, heat can weaken the strength of a magnetic field. This is because high temperatures can cause the atoms within a magnetic material to vibrate more, disrupting the alignment of their magnetic moments and weakening the overall magnetic field.
Many cell phones vibrate when they receive a call. what energy transformation is happening to make the phone vibrate?
Electrical energy to Kinetic energy (Apex 2021)
What form of energy does a buzzer convert electricity?
A buzzer converts electrical energy into sound energy. When electricity flows through the buzzer, it causes a magnetic field to vibrate a membrane or a coil, producing the audible sound.
Which transducer convert electrical energy into sound energy?
Electrical energy is converted to sound energy in loudspeakers and earphones. The basic internal transducers are either magnetic coils or piezo-electric crystals.
What tyes of energy are used to play an electrical guitar?
Well, It depends what type of guitar you are talking about. An acoustic guitar's strings vibrate into the body(sound box) of the guitar and the vibrations resonate in there and escape through the hole. An electric guitar however, has it's strings vibrate and magnetic coils pick up the vibrations and convert them into electrical power, through a chord, and into the amplifier. Then Bon Scott yelled "Let there be guitar!..."
How are electromagnetic waves different from other types of waves, and why are electromagnetic waves classified as transverse waves?
Electromagnetic waves are different from other types of waves because they do not require a medium to travel through, unlike sound waves which need a medium like air or water. Electromagnetic waves are classified as transverse waves because their oscillations are perpendicular to the direction of their propagation. This means that the electric and magnetic fields in electromagnetic waves vibrate at right angles to the direction the wave is moving.
What are the four ways you can make an object vibrate?
You can make an object vibrate by plucking it, hitting it, blowing air over it, or applying an electrical current.
